If I were to build a nice 383/393/408 stroker and add 10 lbs of boost ( supercharger ) to it, I'd hope to make 550-600 streetable horsepower or maybe even a little more. Are the roller blocks capable of handling that? I've heard they're good to 700+ horsepower, but don't have any proof of that.

Thanks in advance for the help. Now, what do you think???
Hi Ron,

I'd second what J said on power. A n/a 408 w/450-500 rwhp on pump gas is very doable & a blast to drive. It just takes a well matched combination. J & I can steer you to the right people to put together a the right combination of parts.

What do you want to do with the motor, is it for the '65 or the fox body?

If you have the time, check out the www.hardcore50.com SBF forum. There are some very capable builders there that offer advice. The bulk of the list is drag racing oriented but, these guys do street/strip & road racing motors too. A quick search there on 408 combinations will yield page after page of threads on various combinations from mild to wild.

We have to meet up at a cruise this year. I have a lot more time now as I was just laid off after 19 years on the job.
