And the reason I asking about 525 B1 motor making 1050hp is, that was my target number for my 572.
After just building a max effort.. 15:1 572 w/ B1 originals, my goal was 1000hp... The best we could get out of it was 960-ish hp... and thats with .900 inch lift cam and ported heads that flowed 415 cfm.. Good luck with your build..
