ultimate street 318

1wild&crazyguy said

I would do a couple of things..

1. would be a 11.1 comp w5 headed solid roller setup with 5 speed rev'n 7800-8rpm w/4.30 gears

2. would be a 390 11.1 comp w2 headed solid roller with 5 speed rev'n 7200rpm.w/3.73 gears

thats if I had money to play around.

whats your idea of street though?

#1 there sounds like alot of fun but that would probably get on the edge of how much rpm can be used in a safe way without sacrificing valvetrainstability with a 59degre motor, some years ago i just once hit over 8000rpms with a solidrollercamed 340 (that i shifted at 7500rpm all the time for a longtime) and it just cost me one pushrod (3/8" chromemolly pushrod), and im glad that pushrod just got slightly bent and nothing more cause that would have been a total disaster probably blowing the entire motor.

im very partial on my take on an ultimate street318 but i would build a rollercamed 7000+rpm motor with a twinscrew, thats what im doing right now for myself but based on a 340, almost wish i was building a 318 instead with the same parts,just to anoy the ford,chevy and bigblock moparguys:toothy10:
