That's a really interesting build, I can't say I've seen any max effort 572's with standard exhaust port heads. If that was dialed back a bit with a conventional wet sump and TF270's (assume the TF's are giving up 40 cfm over prepped 325's?), what would you expect that motor to make? 750-ish with a lower HP peak because the ports really aren't big enough for a 572?
