I want to see what these LS6 heads are going to do on this big cube motor. I've also been waiting to see a big EPS cam out there since the small ones make big numbers.

Cam specs?

You can't run the LS7 heads on a 4 inch bore. The WCCH Stage 3 L92 heads flow 380 which is right there with the LS7 heads. My 427 is 4 inch stoke and 4.125 bore which works a little better because of less valve shrouding.

Good luck.

Exhaust Lobe 258 Degrees @ .050" Tappet Lift with .647 Total Lift (1.7
Rocker)

The lobe separation on the cam is 112 degrees with 2 degrees advance.

My brother and I would both highly recommend steering clear of the 12-bolt.

Don't get a 12 bolt. MWC Fab 9" is where it's at. I love mine.

Ok motor is in now and running great I did do some changes tho

Now it on E85 and bumped the CR to 13:1.

It was crazy when i measured the pushrods because it now needed two different sizes.

Hard to say with the heads and intake.Should be over 500rw no problem.

My 427ci had ETP heads and a 240 Cam but ran a SV intake. Made 580hp/540tq. Lost 25hp with the fast up top.

Thats what I see.

I work at Lethal performance and I have seen this motor make 580 on 225 AFR heads so 550 should not be hard.
