390 stroker ?

390 strokers perform just as good as a 408. Cost the same, so if you have a 318 you want to use, go for it. For the power level your looking for, warmed over, bowl ported stock J heads will work just fine. A 1.94/1.60 valve set will work good. Weiand Stealth intake, Voodoo 60404, 750 carb. Its a must in my shop to install main studs with any HP or stroker combo. Oiling mods should be done, as well as the Canton oil filter plate http://www.summitracing.com/parts/CTR-22-575/ and Cloyes timing tensioner http://www.summitracing.com/parts/CLO-9-5387/.

It should make at least 425hp and 500+tq, have nice street manners and pull hard.
