An update to this post since I just got back from the dyno with another combo.

Same basic 505 with 13.5 compression, CNC EZ heads, 440-2 intake, 1050 Dominator, Comp Cam MM305 flat tappet grind, 2 inch headers, super stock oil pan. 740 hp at 6400 rpm, 640 ft-lbs of torque at 5500 rpm.

This is a reasonable package that most guys could afford. 440Source crank, SCAT rods, Diamond pistons, Comp shelf cam, etc. I ran Schubeck lifters due to the cam changes that I do. A std set of lifters should live with this cam though if the break in is done carefully. Here is a picture for the archives.
