I wanted 537 but there are two guesses at that number already. So I will go 538.

Didn't you use to run these contests with uncorrected numbers being the criteria? I'm in favor of that myself.

Thanks for keeping our minds engaged.

Interesting, pretty similar build to what you provided me with Brent, except for the cam specs.

My SWAG is 532.

[Sand hauler]

565 hp

[64gal482]

Also similar build as my 445 you specked a cam for, going to GUESS 521 HP and 545 TQ.

Almost 1.4 hp per cube. I wasn't expecting that. Those heads are better than I thought. Nice job, Brent!

My 549 HP guestimate was close!

Doug, hp/ci is 1.23.  But they are good heads!
