Re: 1990 rs 305 vs other fbodies

with 2.77's, auto, and a tbi 305, there isn't much your gonna beat at all. You will get the 3.1, but depending on gears and tranny the 3.4 might run with you and the 3.8 will win.

In all honestly your not going to beat anything other than a 3.1 sure thing. Hell i bet my 4 cyl chrysler would give you a good run from a roll. You mentioned the lt1 which is in a totally different league.

ANYTHING LESS that a good running L98 (with some "tinkering") will NOT BEAT ANYTHING.

Honestly. You would probably beat the 3.1 car pretty good. The 4th gen v6 cars would beat you and the Lt1 would put bus lengths on you.

Re: 1990 rs 305 vs other fbodies

I'm honestly not looking to put any money into the little 305, in my opinion it isn't worth it when I can buy a 350 rebuilt with no miles for 300-500 dollars and get just as much power out of it than I can with 1000 dollars into the 305
