340, How much horsepower? 1/4 mile time?

I will say with traction and a good tune (timing/carberation!)you should be 12.50s,as said 28in. tire and 4.10s you wont be maxed out by the traps-especially with that cam.Heck if the heads flow decent you sould see 12 teens,this is based on what the cars run around here with similar builds.For example theres a guy running a dart sport (all steel) with a non ported head 340,3.23s and a four gear running 12.90s and overall its pretty mild.
