408 rebuild
I bought a 408 from Blueprint engines a couple of years ago. They use a 360 magnum block and modified Edelbrock heads with a hyd roller cam/lifters. At 10:1 it dynoed at 465HP and was a real runner. You can go to their website and look at that build to see what parts they use to get an idea. I matched that engine to a 727 and 3500 stall PTC 9.5 converter. Had quite a time keeping the power to the ground. Think in the end it is not how much power you have under your toe, but how much you can get (and keep) to the ground!
