BOSS 302

you have 340 flywheel hp, find out exactly what your car weighs and go here1/4 Mile ET Calculator
if your aod has a shift kit and high performance valvebody w/4:10s and
drag radials id say high 12s, and since you have forged internals id go the low cost big result route and slap a 200hp shot wet nitrous kit and run low 11s! even 10s are possible with that block -its strong as hell
 
turbo all day!! Just bought the boss motor myself to replace my stock block combo. I bought the x302b version and swapped the cam out for an f303 right away. It is NA right now but I will get the turbo back on and tuned hopefuly by next month. Feels strong NA about the same as my stocker with my TFS kit on it. We will see how it does with some boost. My TFS combo on a stock 302 bottom end made 500hp with 7#s but only for a while then it went to knocking. Nothing $6000.00 of boss 302 can't fix.
