I was impressed by PRCs 265 LS7 head. wonder if they are tweaking that for a smaller (LS3) bore.

I'll see if Jason will post the engine dyno sheets. The chassis dyno of this car doesn't have "just" the heads-only swap, it received the new heads, new cam, and a Yank converter for the races. There isn't a good way to compare A-B testing with the chassis dyno results.

i'm not sure if I missed it but what size/type valves are being used in these heads? If they are stock ls7 intake, then how is shrouding on smaller bore (4.065). I am looking to build a 416/418 using Ls7 crank and rods with custom lightweight pistons and am researching heads for this setup. It is going in an RX7 which only weighs 2800lbs and prefer heads and intake that make power mid to up top. Hoping to be able to turn 7k. want a light weight rotating assembly and valvetrain. Looks like this might be a good option with the LS7 intake to meet those criteria. Any other good options for a stroked ls3? Has pricing been released yet.
