LA360 compression

What is it that YOU want the engine to do? If you told him you wanted a 700hp small block he may be telling you that you can’t get there with your combination of parts. Alan Prusiensky is well know in pro stock and doesn’t build junk. If you told him you just want a 300hp street engine his opinion might change. How in the hell are KB107s .100 below deck?? That seems strange to me. Are you sure about that measurement?
@TT5.9mag I told him I definitely didn't want a dog, but I also don't need crazy hp. I would be happy with anything close to 400 hp with good torque. We spoke for a while about it, and he suggested the stroke to take advantage of all the lost quench I'm giving up. As for the .100 below deck, he brought the motor to TDC and the piston was at least .100 below. I asked about just changing the pistons but he said no.
