340 Build

I want it to have between 450-500 hp.

Thats reason number 1 to go stroker - i just made 511 hp with stock eddy heads - so 450 out of iron heads should be doable

I want it to be Streetable, and be able to cruise in it without problems.

reason #2 to go stroker - with a 3.31 stroke you;d have to spin it alot higher to get that hp - with a stroker you still get street manners, and I have 500 ft lbs of torque from 3 grand to 5600 - perfect to save wear and tear, as well as keeping the rpm's down

check out my build thread - mine idles at 750 with a nice rumble, you;d never know it has a stroker in it as you pull up at a car show and could probably run a low 11 / high 10 with the current setup
