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

I think the type of power adder, who built the engine, tuner and who is running it all make a difference on how much power a block can handle. I’ve known guys that can’t keep a 400hp combo from splattering up the track and I’ve got a friend that ran a Fox Mustang in a stock block class, that’s stock block, rods, crank and piston in the 8s. The 5.0 Ford block is supposed to be good for about 550hp before it splits.
