'Pop's Engine' another 440 on the dyno.

We made two more pulls this morning and made 552 LB-FT @ 5400 and 657 HP @ 6600, 658 HP @ 6700 and 652 HP @ 6800, then valve float. I wonder what would happen if we had a correct camshaft in there? This one just isn't right (too much duration) for the engine design as we have only 120 psi cranking compression. I gotta pull the 440 off the dyno because we are dynoing a 496 BB Chevy for a guy tomorrow. When Pop's goes back on we will have the XE285HL cam back in it for further tests with the EZ heads.
