we did flycut,just about any decent sized cam with l92's will require flycutting the pistons.the heads were in the mid 60's,can't remember off the top of my head exactly

nice work guys it appears to be more in the heads as Ed regularly points out in his posts. they love lift im sure the cam has plenty of it lol. In Australia we have been seeing 480rwhp on mainlines and DDs ie load not inertia dynos from time to time. This is using WCCH fine creations and also Higgins heads. A guy just pulled 480 with a 233 233 112 single pattern on a mainline too, we dont have dynojets.
Hopefully we see more results from you guys with tough 6L. Now the challenge is there to get more bottom end as pointed out already, whilst still holding 500 is it possible?

I currently looking for a big cam for 6.0 that will be great in my next 408 stroker. How do you think your cam will perform with around 10:1? Ported L92 heads with ported LS3 intake. thanks

It's not a choice, my 6.0L engine is a 07 LY6 with dish piston. Stock compression is around 9.5:1. Its a budget build for the next summer, so I'll mill the heads .030" to bump compression around 10:1, port the heads, put a big cam in it. Next year, I will build a 408 stroker with around 11:1 of compression with the same setup.
