**600hp sbm block limit? Or is it bs!!**
So what would be your max limit using a stock 360 block.
It depends. No more than 600 for a relatively low rpm drag engine. For a circle track engine 500. Maybe 525. If you want it to live.
And that’s figuring reasonable compression ratios, like 12:1. Up the compression ratio, the rpm, the stroke or a combination of them all and it goes down quick.
A 550 8,000 rpm stock stroke 340 I wouldn’t not do with a stock block. A 650 6,000 rpm 3.75 stroke would make me cringe, but if I was dirt poor and eating crackers I would do it. After that, I figure out how to get my income up so I could afford to race or find another hobby.
Of course, ring seal and main bearing life would certainly be compromised in those scenarios.
