well, I'm done. The whole shebang...

With stock stroke? I'd be really surprised if you don't make at least 550 horse, somewhere in the 6500+ area. I've been looking at doing about the same idea with my 340 (either w9 or SB victor heads, 11.5:1, big roller cam etc). But keeping the stroke stock (so I can still call it a "340"). And I ballpark 550-600 horse depending on final setup. Your's should have more torque.

So I'm very curious what you end up making with this setup.
