I have a 351 stroker motor with forged crank H-beam rods billet caps roller rockers and keep a close eye on maintainence .I have close to 600 hp <I am told> It is a 427 man o war block rated for 1000 hp. I do see 6500 rpm quite a lot that is where the limiter is set. Given these facts how many miles should I expect to see out of this motor.
