I would just like to know if say the Super Pro Bullet 306/308 short blocks for $2999-3449 can be trusted for there advertized horsepower capabilities. 650 horsepower is a lot for a stock block even if it has reinforced Main supports. Not doubting there claims but does anyone know info on useing stock blocks with 650 horsepower ? Cause all the stories I have heard of people going over 550 and its all over for the small block....

thanks

i'm staying at below 550hp,because my friend is on his 3rd block keeps cracking around the webbing by your mains. hope that answers your questions..because i'm starting too ??????? that claim also.

So it prolly is a good idea to invest in the R302 block then after all. Expensive but looks like its worth it....

Better to spend a little more now than have to fix a big problem later. I'd definitely get an aftermarket block if you want those kinds of numbers.

I've heard and seen alot of bad things happen with DSS stuff. Dunno it could just be a "fluke" thing. *Shrug*

your option are a dart block (dont think they just drop in either) , r block , and a sportsman block . i have heard of there stuff not being good sometimes also . and the ctlinder scratches which was on the corral a while i have personally seen ,. a main support is nice al long as the weakest point (block) can take it .

So the only options are only bad ones ? I dont get it. Which one is best for like say 600-800 horsepower ?
