800 hp n/a with All Pro Heads Here are results of a recent dyno test of our 436 cu. in. LS engine package using All Pro LSW cylinder heads ported by WCCH. As with everything we get from WCCH, the work on these heads was top quality. The engine is a Darton Sleeved block with Callies rotating assembly, CP Pistons, Comp Cams solid roller cam, GMPP LS7-style intake, custom 4150 Holley Carb, and American Racing stepped headers. We are looking to get even more power out of this package in the near future.

let me be the first to say "HOLY ****!!"
800hp and 600lb out of a 436ci NA motor?? How the F did that happen?
that would be like 650hp out of a LS2 NA. How is that accomplished?

I know of one that should make 100 more than that.
This kind of stuff is not cheap. This kind of power comes from attention to detail. A thousandth here and a thousandth there may not seem like much, but it adds up.
BTW very nice results on the 436, very, very nice. Stout number, especially with the rpm you pulled it at.

99blancoSS - I'm sure you will be very happy with your All Pro heads.
The CR on our 436 is 14:1.
We were very happy with the engine torque and hp numbers - peak torque and hp were achieved at 6500 and 6900 rpm, respectively - without having to rev into the stratosphere . This engine was designed to have a broad powerband, not just for impressive peak numbers (no dyno queen here). The engine averaged 610 ft-lbs and 709 hp between 5000-7200 rpm. We have more testing planned to evaluate some intake and exhaust mods currently in work and will post the results.
