build a nice torquey 383 stroker. 450hp out of a stock stroke 383 isn't necessarily "streetable" depending on what you really mean by that. Does "streetable" mean "the ability to drive the car on the street" or does it mean a mellow idle, high vacuum, pump gas motor that doesn't have to be revved to the moon to make decent power?
For the stated purpose, if I was trying to keep the costs down, I'd spend the money on the stroker kit before the heads....
