You are correct Pat. Too many variables to factor. New heads would require a custom cam. Would be interesting to see a head swap and then a custom cam swap. I know my 402 sure benefitted from a head swap, however the cam swap only yielded +2 rwhp while losing -2 rwtq.
pat have you spec'd a 500hp L92 cam yet?
This car is being set up for road racing and the mile as 98aggie posted. The clutch of choice will be a Z06 clutch from GM. There wont be any 1/4 mile times in this car, sorry. I plan to leave it well enough alone for now and get the coil overs installed next. However, I am already planning the next engine build for it when this one lets go. Thanks again Patrick for your time to get this just right for me. I am very aware that Im a pain in the **** when it comes to my cars
Now its time to get on with that F-body build

Yes, several. The problem with the 6.0L and 6.2L L92 builds are that they are limited on piston to valve clearance. Anything over a 230-231 intake duration and anything earlier than a 112 intake centerline makes P to V tighter than .080". Many companies like selling cams that push P to V clearance tighter than this, but I'm not one of them. I don't like being blamed for kabooms.
Still, most of the items that Robert used on this LS2 build would help gain power on a 6.0L or 6.2L L92/LS3 head application:
FAST 102 LSX-R intake manifold (unported)
Nick Williams 102mm throttle body
4" straight pipe MAF-less or 105mm LPE MAF
Calloway Honker CAI
American Racing headers 1 7/8" with no cats
Custom cam, springs, retainers, DOD/VVT delete (if applicable)
Yella Terra Ultra Lite rockers
11/32" pushrods
UD pulley
Plus a razor sharp tune

great power. I am still lost on the fast 102 setup. Recently we put it on a 427 motor the 102 lost power compaired to the 92 but then you see threads like this where it worked great. I dont understand.

Was the 102 ported? The reason why I ask is because the 102 is better from the factory than the 92 was and some companies are making them WORSE by porting them. Another thing, the injector boss is a little different on the 102 and some heads may like the spray angle better than others.

Congrats!!!! goes to show you what pairing parts correctly does. I've been following Pat G for a few years now and he always makes awesome power from 243 heads especially now with the EPS lobes.

I saw this car/dyno session in person. Robert has 1 bad A$$ car.
Coach
PS. Patrick, Kurt & Robert, thanks again for all the help Sunday. Maybe we can do some good at No Problem.
