Usable power for the street?

Also, I agree with what was said above. Torque converter and gears are huge! I was cheap and haven't invested in a converter yet but will. I have 3.23 gears and sure grip. I spin all the way through 1st and into 2nd, but I still dont have enough kick you in throat power... soon :)
It's just not something to get the slide rule and calculators out to figure out. 220-236 @.050 on a 108-112 LSA with 9:1 compression with a decent carburetor intake and headers will make any first timer or even seasoned car guy grin from ear to ear. I could pick parts out tonight in 10 minutes that'd give a guaranteed 350-360HP with no sweat.....yet guys come on here and get driven crazy by people who may not even have a CAR over what parts to use. It's just not that difficult. You've found it out first hand.
