Ok, so let's say I had access to some heads off the LS3 from an 08 Vette. Would they be a good head on a 6.0 that I will build my wife's truck? I understand that I will have to swap the intake out since her's is cathedral ports and the L92s are rectangle. I test drove an 07 Escalade for her and she said she didn't like it. I was very pleased with the power it had and the way it pulled. If those heads will work and will make good power with a cam that was very seamless then I might be interested in the swap. What are the combustion chamber sizes and what kind of cam would be best suited for that motor with those heads? What range cam seems to be working best in those heads with that intake?

 

They're 70 cc chambers, yes they would be a good head, you'll want a decent cam to take advantage of the flow numbers though.

Lift 0.200" 0.300" 0.400" 0.500" 0.600"
Intake 151 208 256 294 316
Exhaust 111 152 174 183 189

 

I have been told that the deck on them isn't very thick in a boosted application. I was thinking about maybe running the heads and intake on my 408 for my Camaro but if that is true it wouldn't be good with my power goals and the amount of boost I plan to run.

 

To me, the swap just isn't worth it. Because for the price it will cost me to get the heads, intake, and new TB I can get some nicely ported LS6 heads.

 

How good is that intake and etc? I know that the heads are supposed to be awesome but would a worked set of 243s or something like that be better?

 

theres no comparison, well i hadnt seen any, now if i am wrong someone post up some dyno numbers!!! myself done the l92 swap and by far very pleased with it!!! 440 + rwhp 450+ tq isnt bad at all!! and i feel i still can grab more rwhp out of it

i guess its a price you pay to reach a goal
