572 big block dyno test

Yeah, I don't expect much power increase since I had really good luck with the EZ heads on my old 514. That engine made 900 hp and I've never had a 440-1 head engine on the dyno that has made that much power. But, that could be a corner case. The 514 punched way above its weight for some unknown reason. Perhaps it was a perfect storm type of combination?

I do think this 572 will pick up power from the extra air since it had to be sucking thru a straw. If I was going to bet on it I'd say the engine will step up from 860 to 900 but I could be wrong. I'm not sure we'll find out since I don't think the owner wants to put it back on the dyno. The car was running good, everything is staying the same except for the heads so they are just going to put it back together and go racing.

We have another 440-1 CNC 345 head engine going on the dyno in a few weeks so that will interesting. The owner said it made 925 hp on a different dyno. Sound really high to me but I guess we'll find out. I've never seen a box stock -1 make that kind of power but who knows.
