I want to know how much these engine weigh with and without the auto transmission that came with the engine or would be used with the engine. Is there a lot or significant amount of difference in weight.
2.8

3800

4.9

SBC

Don't know the weight of the engine but my Formula with the SC3800 and Getrag 5 sp weighs 2868. That figure is with 1/2 tank of gas pw, pdl, air, spare tire and jack and about 10lbs of assorted crap

What is stock weight?

My sorces say 2.8 345lbs
4.9 355lbs
5.7 586lbs

hey skitime
stock fieroz are right around 2900 lbs, give or take 80-90 lbs.

the door sticker on my fast back is 2975 lbs
origionally in stock form it was a 87 SE, V6/auto, no sunroof, no ac, only had pwr windows as options.

My V8 reads 2959 on the sill, that car was a 85 GT V6/auto, sunroof, pwr windows and mirrors, no ac.

Why the 87 shows heavier, i dont know, I would think the sunroof glass would be heavier, and other than that they would be close.

Standard transmission cars by nature are heavier, a auto transaxle stripped of brackets and drained alomost completely weighs 187 pounds. not sure on exact weight of a std tranny., but they cant be much more than 75 -80 pounds.

Looks like the Caddy 4.9 would allow the use of stock springs. Nice balance of power to weight. I know the SC 3800 is heavier than the 2.8 but I can't find the exact weight right now. Anybody have that handy. I do think the Caddy auto trans is quite a bit heavier than the 125.

Can't tell you what the engine weights, but my 88 GT 5spd with all options, and Corvette L98 with alum. heads tipped the scales at 2910 wet (full tank) after the conversion. That's with a 4 core radiator, and larger tires/wheels all around.

door # weights are GVW thats gross with loads
people plus some stuff or max weight not what a empty cars weights.
GVW are about 400lbs over net or empty weights
anybody weight the 4 corners to see what each wheels loads is????
tip from a racer said try to get each front wheel to be nearly the same weight/loads and same for the two rears may be nessary to add weight to the lite side to get near the equal for each wheel on the axel.
very good idea if hi-powered swap is used.
don't forget you weight balance is with driver in place.

good idea, I'll run the V8 to the scales ( reads land fill site) and have it weighed

Not that you mentioned it, but the 3400series V6 is at least 50lbs lighter than the 2.8.

Did you get your car in my book yet????

The 3400 engine has aluminum heads, which makes it lighter.

------------------

I didnt think you could use the alum. heads with the fiero intake? or can you with the camero 3400?

88form do you have alum heads?

The 3400 is a FWD block. I wouldn't use the stock Fiero intake... too restrictive. The Aluminum GenIII heads have larger valves than all the others, fast-burn heart shaped chambers and you can pick them up with one finger. The intake has larger ports. I did have to engineer a few parts to put it in.

Some creative scoop/vent work is necesssary on the deck lid unless you want to relocate the alternator.

Desktop Dyno says 300hp. Too bad I'm going to have 200lbs of stereo.

SBC weighs approx 575 with iron heads and intake. Al heads save 80 lbs and al intake saves 25.

A (dry, no fluids) Northstar weighs about 350lbs. (though a rather poor scale was used)

I was suprised how heavy the Getrag 5-speed is, I'd say closer to 100lbs+.
(but that is just a guess from lifting one, phew. ok, I'm a wuss

Best!

Dave, I'll get the scale out and weigh the 4.9 and a SBC this week. Unfortunately I don't have a 2.8 that's not in a car right now.

I almost forgot, I'll have a series II 3800SC here next week, so I can weigh that too.

Rockcrawl thanks for the effort. I keep hearing opinions about the weight of different engines but few real answers.

I just recently had to get my Fiero weighed because I just did a DITY move. my 85 GT with 4spd and half a tank of gas weighed in at 2640 or somewhere around there.

I didn't think the fast back versions weighed that much more.

I was wondering the same thing. I have a 2.8 now and am going to an L67 this winter. I was also wondering the weight difference between the 125 transmission and the 4t65e. thanks.
