SBC Pro Action 14 degree heads

[Ricky Mcconathy]

How bad ass are the 14º heads? How about this:

Scott Parks Runs 6.776/197.59/-0.644, Now #5 A/ND Index: 7.42

Record: 6.810/191.95

Congrats Chad, that's one hell of a pass. That certainly raised the bar in the A/ND class. Kinda crazy it took this long for someone to finally go faster than an 81, as I believe 3 different guys have been that fast.
Hopefully these new heads I just finished will give the Parks some competition next year

Thanks Ricky. We changed a few things before the Finals and when I got that text I just about stroked out! LOL..

One thing I do know about the Parks is they hope your guy is fast (anyone actually) because they truly love the competition and it fuels them.

Again thanks, much appreciated..

Haha Larry I have a set going on a 402" as we speak. Debating on a flat top a 14:1 or a dome 16:1 plus. Methanol and Kinsler injection 2.5"x8

these were Dyno numbers "As Run" in the FaceBook Video

14.9:1 CR Q16 Race Gas
Peak TQ = 598.4 at 7000 RPM 0.516-BSFC 368.5=FuelLbs 17.3=Vacuum
Peak HP = 861.5 at 8100 RPM 0.447=BSFC 344.8=FuelLbs 17.2=Vacuum

-------------------------------------------------------------

we just freshened up the Engine recently
did a little more Short Turn + Valve Job work
raised CompRatio 0.9 points from 14.9:1 CR to 15.8:1 CR
and got these Dyno numbers on JeffWales_SBC_March_29_2019

Q16 Race Gas 15.8:1 CR
Peak TQ = 595.7 at both 7000 and 7100 RPM
Peak HP = 877.3 at 8300 RPM ... higher Peak RPM than last years 8100 RPM

just last weekend won another Mud Truck Event with that 877.3 HP Engine

Both Dyno sessions with :
Gary Williams 1080 CFM Carb with Q16 Race Gas
GM Chevy cast aluminum Manifold #285 18deg 5053 with Manifold-to-Head adapter spacers
4.123x3.625= 387.0 cid
36.0 BTDC ignition timing

WOW!!! I guess the X bar get's put in for the 7.50 chassis!! I was figuring around 700 hp....

that's a 387cid SBC .... you should very easily make over 800+ HP with a 402cid SBC , than you thinking only 700 HP

Craig makes 1024 Peak HP @ 9400+ RPM with 15:1 CR and Rotary Hilborn Injectors on Methanol with those Heads on a 407cid SBC

that 387cid would have made at least +15 or more HP if we could have fit
a true Full-Length Race Oil Pan !!!
