Finally got all my parts, today I measured pushrods. With 10.720 deck,.051 head gasket, heads cut to 74.5 cc, (572-13) Isky EZroll bushed lifters and standard core . 510 intake lobe lift .920 base circle cam, pushrods were ordered 10.080 long intakes, 10.050 long exhaust 7/16 dual taper from Manton. I think the cam is a bit tight, so that may hold up progress till I get that corrected. Not sure how long it will take me to get this thing back together. My beautiful bride of 30 years is battling serious illness, and obviously she gets the attention she needs, this deal comes in a distant second. But this is my sanity project, helping by giving me an outlet from time to time. Link to companion thread,,,; https://board.moparts.org/ubbthread...news-guess-potential-hp.html#Post3061757

Compression works out to 15.61/1 with 74.4 cc heads, positive volume of 3.8cc on piston, .051 x 4.600 bore head gasket, piston above deck . 012 cold. 4.50 bore, 4.560 stroke for 580 cubic inch. Hoping to see some great torque numbers from 6300 rpm up, as converter flashed to 6200 with the 15/1 550 cube 440-1 head combo. As the aluminum block warms, the piston to head distance should grow . 008 to . 010, dropping running compression to 15.16 and raising piston to head clearance from . 039 to . 047 to . 049. Comments welcome.

Building a 572 like you Greg, so following you closely I am too I'm waiting on the crank to get balanced; it is an older used KB top fuel crank with full counterweights on every throw an it has a lot of heavy Mallory metal welded into it for previous balancing. The machine shop is telling me that they can't add any more heavier metal to it now so I need to get a external balanced ATI balancer for it Of course, no one has sone in stock and ATI does not have them schedule to be made this year I have ordered that shell and the hub separately, their supposed to be available now, and I'm hoping to be able to make one soon It is 14,4 to 1compressionn with B1 heads and two kits of NOS on a sheet metal tunnel ram with two Mark Sullens E85 Dominators carbs I'm hoping and expecting 1000 HP with motor only and about 450 HP with the two kits on Scat forged steel power adder H beam rods with L19 bolts with Icon coated shelf pistons and hellfire rings Come on balancer parts

Jesel rockers need to be no less than 1/2 turn from the rocker, and not over 1 1/2 turns out. That is only a . 040 window. If the heads or block get cut, or I choose to run my other rotating assembly, I may not be able to stay inside that 1 turn window on the adjusters.

Keep grinding away Greg! You'll have ignition before long and the HP goal met buddy! Nice chatting the other day - always a great conversation! Thoughts and prayers for Sandy/you/family.

We just got dad's 588 with 572-13 385's dyno'd and picked up from Best Machine a couple weeks ago. Pretty similar build besides we are running a 1250 gas carb setup. You should get close to your goal depending on the dyno. do you have cam specs and fuel type? Compression?

it looks like the vacuum readings stayed pretty steady to me Same thing on the BSFC dip, I wonder why? The AFR on both sides stayed pretty steady, maybe a little rich on the BSFC depending on which fuel they were using
