Ive been working on my 91 rs for about a year, doing small mods when i can. I was wondering if anyone could give me a guesstinate of how much horsepower i have. Im hoping for at least 215-220, but I really have no idea of where its at. Thanx.

lo3
all free tbi mods
no cat
a.i.r system deleted
cam deleted
turbo two two chamber muffler
14x3 chrome air cleaner
cowl hood
b&m shift kit( i know this doesnt make me more hp)

future mods:
lt1 cam
headers
flowmaster 40 series muffler
3.42 gears
ported heads
edlebrock intake
tb from turbocity
b&m rachet shifter

 

You really don't have a cam? See my sig and I might have 200hp. The mods that you have planned will have you on the correct path. The LT1 specs can be found in earlier post's. I have an LT4 cam and only know the specs on it and they are dur 203intake and 210 exhaust lift with 1.5 rockers 446intake and 450exhaust. It probably does not matter which one you get they are all so close. You can but the LT1 used from e-bay or the LT4 new for $140 from Jim Pace chevy. Good luck.

By the way, you probably don't need a bigger tbi unit for a 305 the stock size will go a long way with the mods that you have planned.
