I Fly Low
i started off with a 91 firebird that i had put a 350 in and i blew it up, so i put the motor from my typhoon in it. my typhoon had 90k. its all installed now and it feels pretty good in my firebird.

i'm curious why everyone thinks a turbo 4.3 should be swapped into everything?

Same reason the buick guys think a 3.8 should be in everything.
Not sure what that reason is but there may be one![]()

sounds like a case of "i had it, so i used it."
It makes sense to me, like Mike said if you have it and your car was already a small block. Then it would be pretty much a bolt-in with less weight and alot more power then a stock Firebird had :tup:. It should run really well, I just don't think that I would use a 4.10 gear like he did unless I had a tall tire. I would have went with one of these instead.
1. GU4 Axle, Rear 3.08 Ratio OR 2. GU5 Axle, Rear 3.23 Ratio
its true, i had it so i used it, lol, and i took it out because the truck was wrecked when i picked it up, and the 4.10 is in it from when i ran it with my 350. also its hard to just use any rear end in 3rd and 4th gen birds because they have a stupid (yet effective) torque arm that mounts to the differential. it takes some customizing to eliminate it.
That why I listed these rear ends. 1. GU4 Axle, Rear 3.08 Ratio OR 2. GU5 Axle, Rear 3.23 Ratio because they are for a 3rd and 4th gen birds :tup:.
