When we create a Superchips performance program for your Cadillac, we don't just make a few universal changes at full throttle, we make many changes throughout the powerband, from part throttle through wide open throttle. These changes are made to each vehicles specific computer box code. Our competitors provide you with a "generic" chip, which is dependent only on the year, make, model, engine and transmission of the vehicle.
Why does Superchips tune by computer box code?
The computer code is the manufacturers calibration number that designates the exact programming the vehicle is using. Information such as allowances for high elevation, gasoline condition and climate as well as the vehicle specifics, i.e. year, make, model, specific engine, transmission type, and gear ratios etc are all taken into consideration when we create your Superchips performance program. We use box codes so that we can make the best chip for your specific Cadillac. We do not sell "generic" chips that work on any Cadillac of that model. The small but significant changes that you will only find in a Superchips performance program is what allows us to provide significant performance gains for your Cadillac.
What changes does Superchips make to provide the extra performance you're looking for?
We adjust the ignition timing to take advantage of 91 to 93 octane fuel. We adjust the air fuel ratio We firm up the shifts on automatics We shorten the time it takes the automatic transmission to up shift On some Cadillac, we will raise the rev limiter and speed limiter We do not require the use of a 160 degree thermostat which can cause excessive fuel consumption We can provide custom programming for most aftermarket modifications There's no tricky installation, installation can be performmed by anyone with general mechanical ability. If you can change your own oil and filter and change your own spark plugs, you should be able to perform this installation.

Thx White, and thx cryzone. So welding in the original holes is perfectly safe?
Hehe.. nothing but a brand new non plugged or welded flywheel is perfectly safe. Hopefully it'll hold. I was thinking of putting a scattershield on the back side of the trani when I put it all back together.
I think I'm going to have the holes welded at work and then have a machine shop drill the new pattern and make the metal sleve for the center of the flywheel. You can weld these flywheels, they are cast steel, alittle more friendly than cast iron. I figure it will be stronger than plugging the holes.
I'm sure that would work, but given how fast that flywheel is spinning, and where it is compared to your body, I wouldn't want to take any chances.
In fact, as much as I am a diehard manual transmission person, Ed Parks talked me into taking the automatic tranny if I do the swap. It would rather have the tranny that's designed to work with the engine bolted together.
I'm also worried that Texas is about to get as bad as California in terms of emmisions. I fear getting a 5 sp Cadillac engine past the smog nazis will be a nightmare eventually.
I have the perfect candidate for a torquey - low rpm V8 sitting in my driveway, the economy 4 speed 1984. Far sturdier than an Isuzu 5 speed, probably as strong as a Getrag, 60mph is about 2000 rpm, top speed (can't find the calculations now but somewhere around 140+ at 4500rpm) should be around 130+. Yes it is a very wide ratio transmission, but with that kind of torque and no real revs available it is perfect. I still don't know what I am going to do with that car but I'm thinking.

Ya, I got a 4.10 4speed as well. My goal is to be able to bunny hop or even lift my front tires off the ground slightly....I think that looks so cool. And for the issue of flywheel. I think its about time for one of you canadian 4.9ers to produce and sell flywheels. Don't worry I don't think anyone is worried about warrenty. But if it could be kept under 3 hundred canadian I believe there would be a huge market. I would do it but ya, no machine shops here are resonable.

My question for this is how reliable is the 4.9? I'm sure there's not too many that have been abused by running past red line to many times but by neglect (stretch that oil change...) What's typical for mileage before a rebuild is needed?
Dennis I will second what Jon said. I get comments all the time about why I didn't put in a SBC or a N*. What's a 4.9L? hehe Best bang for the buck is my motto. I did the entire swap only using BubbaJoe's mount set for ~$2500. The amount of info and help available for the DIY'er is amazing. My thanks for helping me with my swap goes to Rockcrawl and PBJ. Is it the fastest thing out there? no way My goal in doing this was to get a 'light to light' car. Something I felt was lacking in the stock V6. The torque that Ed mentioned is right on. I also wanted to get rid of that infernal hydraulic clutch so went with the 4t60e. It's a minivan trans with a final of 3.06--a bit over the stock caddy 2.73. The second best reason for doing a 4.9L swap? I have a spintech muffler and nothing sounds better than V8.

I think You misunderstand, I am referring to the 3.32 ratio 4 speed with the 0.71 fourth gear. The 4.10 would only be useful if you wanted lots of acceleration but didn't care about the buzz on the highway and the lousy gas mileage. 1/8th mile drag racing would be where that tranny would shine, or possibly autocross, but definitely not a daily driver.
I agree about the flywheel, I would love to build a 4.9 but I would need to know that the parts were available since there are no machine shops here to do the work.

Well I had my heart set on a 3800SC but now I have to think twice! SDFiero: $2500 is unbelieveable! Please forgive me if this question has already been answered but........How much more or less would it cost to do this with a manual tranny? Will the 5spd in my 88GT bolt up to any year 4.9L? Please this would be a major deciding factor of wether this swap is for me or not. As much as I hate waking up in the morning and driving a cold 5spd to school or work it just wouldn't be the same when I wanted to 'have a little fun' Thanks for your help--Nathan

Manual trans would cost more. Flywheel is around $500 plus a beefy clutch would set you back atleast $300.
I swore I would never own a auto trans fiero. My 87GT is a 5 speed car. After 10 years of the great fiero clutch issues I decided to use the caddy's 4T60e during my swap. As Ed Parks said "your using the GM engineered trans with the engine it was designed for. It (the tranny) was built to haul around a caddy, do you think your fiero could hurt it"? So, 4T60e it is. Goodbye fiero cutch problems forever!

My sig pic is linked to my site.
Have you had to show anyone your taillights with the 4.9? Can you tell more about the performance of the 4.9 light to light maybe?
[This message has been edited by Mastermind (edited 05-05-2003).]
I have a 1985 coupe with a 5 speed (Isuzu), if I go with the Caddy I would like to switch to the automatic which matches the engine for reliability reasons (too many hassles with clutch on stock engine, and I would prefer to stick with as many stock GM parts as possible). Meanwhile if you bellieve I can have a relatively trouble free daily driver with the Isuzu transmission I would like to hear from you as well. Now for the question:
Other than the obvious items such as the mount kit and the electronics what other major items am I going to need? For example:
Axles? - which do I need, can they work with stock rear bearings?
Radiator? - is the radiator in my car sufficient for the engine, can I run an external transmission cooler without the radiator cooler?
Instruments? - will the stock speedometer and tach work with the new drivetrain? Shifter? - will I need a Fiero automatic shifter or can any other floor shift be adapted? Are there aftermarket shifters that will work?
Handling? - is there any noticable difference in handling after the swap (I notice the weight difference is not all that great, and I would relocate the battery to the front)?
Please, those of you who have done the very swap I am considering, let me know what I am in for. Note that I am in Newfoundland so all of you Canadians let me know what realistic costs in Cdn dollars would be.
The Fiero is tha ideal engine swap candidate these days, there aren't many RWD chassis around other than trucks and old pony cars, and FWD swaps must take into account engine weight (a Caddy V8 or 3800SC in a Cavalier would make for a rather fowl handling beast). With the Fiero you have so many options available.
Mastermind, I have had fun. I can take most cars off the line just because of the torque and power to weight ratio. Last week I had an import trying me on the freeway, all I did was put it to the floor for a couple seconds and the sound of the engine alone made him back off. You shoulda seen his jaw drop. I got blown away bad by a late model Firebird (LS1?) *sigh* I hate the fact that you cant tell them apart anymore. Oh well.
I estimate the car to run 0-60 in 5.2 and quarter mile times around the high 13's. When I get my performance chip I am going to take it down to the local 1/8th strip and will have time slips for you all to compare.
Other than that, all I can say is I have a big smile anytime I am behind the wheel.
From my perspective, if your spinnin' the tires your not moving forward. Want a really fast car? I think the 3800SC is way faster on top end but I would probably still beat it off the line. What's the point when all roads have a posted speed limit. Want raw tire roasting power? Get a SBC. If you roast the tires on your SBC I will probably still take the lead coming off the line. My theory has always been it's not how fast you go - it's how quick you get there.

I guess I did, but then again i guess u misunderstood the 4 speed. It all depends on what your doing with your car right? I want light to light and autocrossing/drag. Second of all, in my opinion(please nobody hate me) and the opinion of a few others, its actually slightly cheaper to go with the manual transmition apposed to the cadilac's. Why? First off, you already own the transmition and you don't have to buy one. With manual transmition you use your stock axels and don't have to go out and buy the cadilac ones. Now, you can get a good clutch for under 200 canadian(cavalier) and hopefully get your flywheel for 200(if you already own one) So they are quite similar in price but with the manual and stock axels you don't have to do any modifying.

I'm curious about what you mean by getting beat pretty bad by the firebird. Can you describe the race? How long was it? Did he beat you out the hole? Or did he caught you after you got the jump on him? How did it go?
BTW was his a stick or automatic?

I had an LT1 Trans Am, 6 Speed which produced about 310 HP at the wheels, I don't think a 4.9L Fiero could hang with it. It pulled like a train in every gear.
The LS1 Trans Am have about 325 HP at the wheels, (conservatively, probably more).

I know it will do 115mph. It runs 60 at idle, 80 at 2000rpm and 110 at 3000. I LOVE IT.
Dont take this the wrong way, but 60mph at idle? Unless it idles at 1500rpm then that is a false claim. I would expect that engine to idle somewhere around 700 rpm which would put speed somewhere around 30mph. (all that is based on 80 @ 2000rpm)

Granted the Trans Am has more torque but it is also heavier and most likely does not have the traction of a Fiero from a dead stop. Therefore, I don't see how it could have beaten the 4.9 badly. Perhaps in the long run yes, but light to light I can't see it whupping the 4.9 badly.

C'mon guys, does anyone have an opinion on the 4.9 vs the Firebird light to light.
Well, I used to own a 94 Firehawk with a few mods it ran 13.2@108 and on the bottle it ran 12.4@118 but It had horrible wheelspin (2.02 best 60ft time). On the street with the LT1 its either bog or spin. Real hard to get a good launch. LS1 is softer on the low end but pulls like a monster mid to top end so wheelspin isnt nearly as bad as the LT1 cars. If its and auto trans LS1.... Hmmm it would be a coin toss. 6 speed car, I would dare say I would put my money on the 4.9.

ehh i thought that shops wouldnt touch the engine??
I wouldn't know. I only had the engine rebuilders rebuild the heads. My gasket kit came with valve stem seals so all that was required was cleaning them up, laping the valves, resurfacing the face (took 12thou off due to alittle warpage) and paint. They look brand new.
Bottom end was easy, take some measurements with a dial caliper and order new bearings. I didn't machine the crank, it looked spotless. So did the bearings but like I said its cheap insurance to replace them especially with a rebuilt top end.
I asked out of curiosity how much it would cost to have the engine rebuilt from scratch and he quoted me somewhere in the $4000-5000 range. I can buy a lot of used engines for that kind of cash. I also asked GM how much cylinder bores are worth for the engine. Each bore comes with piston installed. They are $220 Canadian, or about $1700 for a set. This is definitly not an engine you want to do a complete rebuild on.
Hope this helps

How about it? I see Jesse picked up his car. You have drove both cars now. Can you add anything else on the 4.9 vs Firebird light to light?
No, not really. The auto trans 4.9 fiero comes off the line with zero wheelspin. On the street that should make kick some serious butt red light to red light. As for the F-bodys.... guess you should try to race one or two and see if you are happy with the results.

The attitude and willingness to help from the 4.9 swapper community is fantastic. The swap is not a 'bolt-on', and you will have questions. Everyone (including Ed Parks - who does this for a living) supplies details when asked, including pictures and part numbers to help you along.
