Some of those engines need to go on Jenny Craig pronto.

I question the accuracy of this list. They have the Iron Duke and 60 degree V6 weighing the same. But weight specs for Fieros with the engines are not the same. Also, I have seen another document that has the Iron Duke weighing 20 pounds more than a Chevy Vega 2.3. But that document has it weighing much more.

The list seems a bit old. Engines like the Buick 3.8L and the LS1 weren't on there... as far as I could see.

Corvair engine don't even come close to 300 lbs.
The total weight of the engine is 256 lbs
Engine and Transaxle is just little over 300

That list is stale. It only lists OLD engines that are now obsolete or no longer used.
I published an up to date list a bit over a year ago and it had all of th engines listed that were popular Fiero engines swaps.
I don't remember the weights but I do remember that the 3.4L TDC engine was the heavyweight at a whopping 592 lbs.

Why are you always posting false weight info on the 3.4 tdc when you have been repeatedly corrected in the past. A dressed 3.4 DOHC weighs about 465 lbs with a manual flywheel. Very close to a 3800 sc in weight

You are correct that weight that I posted was inaccurate. Near 600 lbs is getting in to serious V8 territory. What can I say ? I am a terrible typist but spell check doesn't correct engine weights!!!!
The weight of the 3.4TDC is 492 lbs, but still the heaviest V6 that GM ever produced.
The 3800C is not lightweight either but comes in around 448 lbs.

The 4.9 is not on the list either. Mine came in at 372 lbs with a manual flywheel, SPEC 3 clutch, alternator/starter, exhaust manifolds, crossover pipe, and no AC. The 2.8 it replaced weighed 369 lbs as it came out, also with flywheel, clutch, alternator/starter, exhaust manifolds, and no AC. The crossover pipe on the 4.9 was the only piece the 2.8 didn't have.

This list has shown to be very accurate for me at least as far as common fiero swaps goes...

what would the weight be of a GT with a L67 in the trunk? also, what is the weight distribution? i think it would be about 48/52

You're still wrong, by about 30 lbs. I have weighed the DOHC, it is at 465lbs dressed with the DOHC manual flywheel. According to your own weight figure on the 3800, the DOHC comes within 20 lbs of the 3800. If the 3800 weighs that much is it dressed with a manual flywheel?

If I were to use a lightweight flywheel I suspect the DOHC would weigh the same as the 3800, if your figures are right with the 3800 dressed with a manual flywheel.

The engine is not in the trunk. Its ahead of the rear axels. The trunk is behind it. Stock weight dist of a fiero is about 44/56 for V6 auto car. Trans, engine, year, and body work determine the exact amount. With a L67 it gets a bit worse being heavier then the 2.5 or 2.8. 42/58 would be my guess. There are alot of variables and things you can do to change that though. Moving the battery up front for one. Though its heavier you probably won't be able to tell by feel.

Fiero addictions numbers on his site seem to agree with mine on the 3.4L TDC Listed as Chevy 3.4 liter DOHC V6- 492.5 lb. This figure came from an old GM spec sheet and it probably means weight dressed including the A/C compressor. Remember you've got four cams, 16 valves and two massive heads on that engine and does the clutch count? .
Fieroaddictions weight on the 3800SC also seem to agree with my findings at 448 lbs (vs 445). That engine is no lightweight either as a fairly heavy supercharger sits atop and I believe the weight is figured with a torque converter, the A/C comprressor, and all other items.
The winner in the engine swap catagory for weight seems to be the 4.9L although the Ecotec is even lighter but a difficult swap.

I still havent figured out why people post so much on engine weight in terms of 40-50lbs, when there are hundreds available via weight reduction.

If I have to have a iron motor and a 30lb turbo in order to make an extra 200hp, I will gladly take my front bumper support out in order to offset the "horrible handling" that I have seen referenced in other "I dont want to do a motor swap because it will handle like ass" threads.

I weighed mine with the stock AC alt and manual flywheel from the DOHC and it comes out to 465lbs. I did not weigh it with the clutch and pressure plate because I figure that is part of the trans assembly just as I would figure the torque convertor would be for an auto. Besides that the clutch and pressure plate would only add 12 lbs so it would be 477lbs but as mentioned, it really isn't part of the engine . Again if I were to weigh it with a lighweight flywheel such as an aluminum one or a 88 neutral balance Fiero flywheel which weighs 12 lbs, which can be used on the DOHC, the engine would weigh less.

When I weighed it bare without acc it was @ 400 lbs. I even weighed each sub assembly.. dont have the figures for the parts but when all was added up it came out to 465 lbs. Also, I am well aware of what the DOHC has for cams and am prettty sure the heads with cam boxes and cams weigh close to what iron 2.8 heads weigh ...

Have you weighed a L67 dressed and undressed? Weigh one with a manual trans flywheel and all acc and see what it comes up to and then we can compare

I have an identical 88 GT with a stock engine and manual and have taken it through the twisties and it handles just the same as my 88 GT with the DOHC. I even used the same tires for each test.

GM has weights of current engines in the spec sheets here:

Unfortunately they do not have the ecotecs weight which is what I was looking for. Interesting that the LLT is only 40lbs lighter than the LS3.

I was close ~41/59.
