I think his issue is the wrong wheels spin. More HP ain't gonna work to well in the long run.
L^? What heads? LS6?

Ha yes LS6 not L^6 I try to tell him in my opinion its the heads cam package but he insisted that it wasn't IDK why he thought he wouuld gain much from stock stuff if he put a bigger cam rockers springs and a intake but I would like to talk to some LS4 guys if there are any one here.

I dont know much about the LS4/5.3L, but the hp to the wheels may seem low because of where he got it dyno'd or tuned. And although the LS6 heads flow better, the chambers are larger than the 5.3 heads...less compression.
He should see gains, but dont expect the same type of gains as you would from an ls1 with ls6 heads and cam.
LS4 is a fancy way of saying truck motor.

theres nothing wrong with an ls6 cam, but its not going to net him much. From what Ive read from the 5.3 guys, the 224/224 is popular and around the 230's is big. The ls6 is 204/218.
I would guess that a 5.3 with the ls6 h/c should be around 340-350 hp with proper supporting mods and tune.
You said he got smacked by cars with 300 hp...a 50 hp difference is not that big taking into consideration other variables like weight and gear. This is also based off the assumption that his car is properly setup.

Unloading the tires at launch is a bad thing.

That sounds really low for power to the wheels....especially with heads/cam(even if they are OEM parts).

ls6 heads on a ls4 are redundant. the ls4 comes with ls6 heads stock. as for the ls6 cam im going to call bs on that since the bolt patterns at the end of the cam for the ls4 are single bolt, where as the ls6 cams are 3 bolts. also im pretty sure any cam for the ls4 is going to have to be custom ground especially since you still need to get around the DOD
sounds like his cars stock with exhaust

I thought they had AFM, not DOD (like the G8 or Camaro).

Oh, wait, am I'm thinking of VVT? With the cam phasers? AFM is electronic and VVT has mechanical components, no? Stupid new confusing things. lol

alot of guys get rid of the dod. and install standard lifters due to the dod failures.
so it is possible for the ls6 cam in it w/dod out of it.
not sticking up for the guy. I think he's a moron.
should have slapped l76/l92 heads & intake if he wanted more hp without breakin the bank.

yeah but then he'd still need an adapter made for the bolts in the cam sprocket...
edit:......also as someone to mention it has ls6 heads on his mod list, when it comes stock doesnt sound very reputable

not neccesarily, just use a 3 bolt cam sprocket.
ANYWAY, the real s*** here is that the dude showed up and thought he was talking good s*** that he got ls6 heads & cam. when indeed he probably has nothing done and he is full chet.

ls1 ls2 ls6 ls4 lq4 lg9 all of them have the same basis for an engine and almost all parts are interchangable.
my motor is consisted of ls1, lq9,ls7 & l76/92 parts.

i also thought the fact that the ls4 block is shorter is the reason you couldnt use a regular ls cam....like i said i only touch base on these...this is just from what ive read over the past few years sicne its been out

FWIR the crank is shorter. Doesn't sound useful for swaps.

Do you have the info on their slips? Would be interesting to see how they each got off the line and what the traps were.
