Quote: The point I was trying to get at is a $3500 after market block, a $2000 Callies crank, $1200 Aluminum rods, $4000+ heads, isn't required for 650 hp. Sure, you can dump $15K+++ in the project if you want, but it really isn't needed.
That is definetly true. But I dont think I would want to push a stock block much more the 650 hp. I would say my 493 is pushing about 600 to 610 hp and so far no problems at all with my stock block. Ron
Yeah, Ron, 650hp is my personal limit on a stock block and an 18 spline. Some main caps and a girdle and call it good. I already have the girdle kit, just need to get the caps. One of these days I'm going to use that 512 rotating assembly in the shed.
I think the HP estimate of your combo is pretty close.
