- - 3345lbs (https://www.thirdgen.org/forums/tech-general-engine/478244-3345lbs.html)

I figured my 88 formula with a/c delete, 700R4 delete, leather power seat delete, heavy stock manifolds delete, and TPI delete would be about 3200-3250.

Wrong, try around 3450-3600

T56? That would add quite a bit of weight over a T5... they weigh about the same as a 700R4 from what I've heard, and they are quite heavy. I'd bet a T56 is a good 80lbs over the weight of a T5.

What do you mean wrong? I just weighed my car and it's 3345.

Adam, the T56 is/was in my 86 Trans Am, not my 88 Formula. Formula has a T5 instead of the stock 700R4.

my car weighs 3288 no driver..and no weight reduction..

Ahh, ok.. I dunno, couldn't tell you what would weigh that car down so much. My '83 Z28, which is basically stock, weight-wise except for the T10 4-spd, weighs less than that. I would have thought your fibreglass hood (assuming that RA hood is 'glass..?) and the ZR1 wheels would have helped out some.

Still have the 10 bolt in it, or change up to a 12 bolt/9"? Those aftermarket rear ends are a good 80-100lbs heavier than the stock 10 bolt.

I've got Z06 wheels on the car now, fiberglass hood, the corbeau seats, and the 10bolt from an 01 SS with LS1 brakes.
