Stock 4.9 1/4 mile times? (Page 6/29)
MaxCubes AUG 29, 10:01 PM

I would bolt on a Holley 670cfm Pro-jection stand alone 2 barrel TBI system on that manifold... You can find them easily on ebay for around $500 complete..... better than running the stock tbi and computer.

The fuel distribution on that thing must be horrid. Some lean, some rich... Geez you guys, why even bother with this motor? I really dont get it. The amount of time and energy and money and weight you guys are wasting blows my mind.

Just out of curiosity what motor are you running in your car ?
Have you ever had one of these in your car to evaluate it's performance?
Which motor do you recommend to put in my car that you think is the best swap?

Just curious so I would like to hear from you what you think.

One key factor in ET's is the FDR. The Cadillac 4T60E trannys typically had la ow numeric FDR like 2.73. THis ratio may be great for highway crusing but not optimal for drag racing. LOcate a 4T60E w a 3.33:1 FDR and my prediction is that your 4.9L will "blast off". The question then becomes, do we have any revs left at the end of the 1/4 mile w the 4.9L using the 3.33 FDR.
BTW, PBJ is achieving great performance with a Turbocharged 4.9L not a stock engine. As you might guess turbocharging makes a huge difference in horsepower as PBJ's low 12 ET's show.

If I was doing a 4.9 swap, I would bolt on this puppy. More flow and easily adjustable for best performance. The factory setup is hard to work with.

So please, the stock engine bashing is really lame

I agree that bashing stock engines is lame, but I really wish the bashing of the 3800SC's breaking all the time would cease as well. Where did this rumor come from anyway? Just because 1 or 2 people here with 3800's are breaking "all the time" doesn't mean that ALL 3800's break. The same goes with 4.9 swaps: just because most do 15's or 14's doesn't mean all are "slow".

Yo, Punisher (Jon) ...I have one question. If you're gonna talk so much smack, why is it that your BUDDY's car is the one you want to put up against the 4.9??? Are you even old enough to have a license? Because this sure sounds like high school (or maybe junior high) to me...
Inquiring minds want to know...

If you go back and read real carefull I'll bet you can figure it out....

HINT: 86fieroEarl and his "buddy" are both in FL.

JM, did the saab 6spd ever work out? It'd be a nice compliment to that northstar of yours.

It's a GM piece that's been modified. I bet MTA would make one for you if you gave him some money. Sounds like an aftermarket part to me...

Specific Bolt ons to the 4.9.. The stuff you listed are generic speed parts.

now, now... let's not split hairs.

Lets setup a race and put an end to the debate

I agree.

------------------
Punch the gas and feel the back step sideways; rip off a powershift and hear the tires punished by torque; downshift, lift off and feel the engine braking that only comes from big cubes, listen to the pop and gurgle. Know that you are driving an American V8. There are finer engines made, but none that are this cool.

Luck, Fate and Destiny are words used by those who lack the courage to define their own future
