Good looking power curve. Nice to see that you didn't succumb to over-camming like so many do with L92 heads. Congrats on exceeding your power goals.

Yeah, the scale does look a little funny compared to a lot I find online with 4k-redline reads. I think the SAE number was 523, ill post up the SAE graph this afternoon. Dyno shop was showing everything in STD, that's where I got the 532 number from

Nice results... curves look sexy. How does she idle? That cam is just mild enough to idle stock like in that motor...Should add your build to the 40X build sticky.
