**600hp sbm block limit? Or is it bs!!**

If you fill the block to the bottom of the water ports, it would probably be smart to get an oil cooler too if you drive it.

It's my personal opinion that if one feels they need to do it at all, they should just buy an r block and forget about this thread. I mean after all, we're all confident the block will handle a lot more than 600 hp, right?
Why bother filling it.

I think if Mister T was still with us, he would agree.:thumbup:

I short filled mine for insurance. It's never a bad idea.
