Hi guys thought I'd bounce this one past you and get some opinions as to whether.this is possible or not.

Putting together a combo for a guy with a VZ Commodore (model prior to the G8) running a 6.0L LS2. At this time the car is completely standard, planned combo as follows:

TEA ported TFS 225cc heads, 60cc chamber
Ported FAST 102
102mm NW throttle body
OTR MAFLESS intake & airbox
FAST fuel rails
YT Ultralight rockers 1.7:1
1 7/8" 4-1 long tube headers to dual 3" system
Comp 54-460-11 cam.
3800 stall with lockup.

Mainly after opinions on the cam, do you think 235/243@0.050 on LSL lobes will be 'enough' to get close to his goal? I personally don't expect 500rwhp, the Mainline dynos we use down here read lower than the Dyno Dynamics & Dynojet units, but if we could get into the 480-490 range that would suffice. Oh yes and its a stock short block, not coming apart but we will flycut pistons if required.

Thanks!

People have hit 500rwhp with ls1 cars, i def think you can reach 500 as well, HOWEVER...

I hope you realize, that with the stall you will never actually get to see that 500 number come across from the drivetrain loss

My car was an a4 but was locked converter on dyno jet


I would go with 239/247 lsl/lsl on 111+4

TFS heads for the win! I'm with stupid ^^^^^^

That's a very healthy cam and it is a 113+3 with .621/.624 lift so I believe you might need to fly cut but that's nothing. I believe you'll be really close with those heads touched up by TEA!

Thanks for the info, I modelled that up in EA Pro and it shows a decent increase over the 'off the shelf' LSR grinds. Flycutting if needed isn't an issue, plan is to run the compression ratio into the mid-high 11s.

Converter had to be locker. Those number are hard to come by with a big loose converter.
