Quote: As requested, This is a Aluminum World block, 572" K1 rotating assembly with 91 octane pump gas assembly, Indy 440-1 heads hand ported by Mopar Engines West (These are the actual heads that they made the most power with 765 IIRC in the 2006 Mopar Muscle Engine Challenge), .750 ish Comp roller cam, Indy 440-2 dominator manifold, 1250 Holley carb, KB Gear drive. Car weighs 2750 # with me in it, 4.10 geared dana , 727 with all the good stuff. So far 9.20 @144 in 85* heat and a junk track. This picture clicked the 60' beam at 1.379 (usually 1.27 60') and still ran a 9.29 @ 1.41 with 15 mph headwind on a hot track at 4:30 in the afternoon. Shift at 6800rpm , motor sees more than 7000 through the traps. Car has been 9.04 @ 148 with 501" 14.2/1 comp motor prior, that motor would probably equal this one in these weather conditions but did not have the low end torque that the 572" makes or the weight reduction that this block provides.
Thank you! That's great info! What rocker arms are you running? Have you seen any issues so far spinning it over 7000?
I shift at 6800 and go through traps at 6800 so it stays below 7000 with the 4.10 gear, forgot to mention tires are 33x15x15. Rockers are Harland Sharp on all my race motors.

With my other motor I was going thru the traps at 7050. It's a Glide and 4.56 gears and 32x14.5w slicks.
