Nice work Greg, keep plugging along. We're all in the same slow boat because of delays beyond our control.

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.

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.

I am too boogie
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 confused
Of course, no one has sone in stock and ATI does not have them schedule to be made this year whiney
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 luck
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 luck
I'm hoping and expecting 1000 HP with motor only and about 450 HP with the two kits on luck
Scat forged steel power adder H beam rods with L19 bolts with Icon coated shelf pistons and hellfire rings luck
Come on balancer parts shruggy

Ive got my heads at BES now getting their excellent workover. He said it would take them 5 months. UGHHH. They said 900hp, is very doable, and that’s more than adequate for my bracket motor. I’m wondering how big a carb, or maybe 2 instead of one. I’d post a picture but ill have to have my son help me. I’m building Indy tall deck.

10.080/10.050, Why would you not split the diff and order them all 10.065 ?

pushrod length is critical, or more critical, the higher the lift . 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.

Did you get to find out what that motor would make at peak RPM on the HP?
I'm wondering why the oil pressure started going down before the motor reach peak HP? confusedwork

Cab, I bet it is the vacuum of 14 inch, which would drop the observed on the gauge by about 7 psi.

it looks like the vacuum readings stayed pretty steady to me shruggy
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 confused
