430hp 318 for sale
Why do you need a 430HP 318? Racing? It doesn't sound like a very reliable street engine.
...and before everyone goes off on me, I'm not saying that there aren't 400+ hp 318's running around. All I'm saying is that there are far more reliable ways to pump out 430 hp, on the street. A big block, for example, and it does it without working hard, or being as finicky as a max pumped 318, and are not prone to catastrophic failure like an engine that needs to run on the edge to make that kind of power.
If you're a small block guy, 360's can make 400+ HP pretty inexpensively, and more reliably, too.
