Nice numbers! I finally got mine figured out too. I have a very similar build but I have l92 heads, fast102 setup , similar cam but on a 115lsa. I have it at 10.2-1 compression for when I put the blower on it. Still a blast to drive NA tho

You have very stout numbers? But how come all these LS3 guys are claiming they can touch 600rwhp? When yours is setup nicely and you have more cubes and got 500rwhp? granted you could change headers and put the fast on it and pickup abit

maybe with top of the line heads, fast, headers and every imaginable bolt on such as UD pulley?? 600rwhp is still not very believable on an LS3.

1 7/8, 3" Y, 4" Mufflex and you will see hp/tq gains everywhere. Sell ur stuff to justify the upgrade. . Great numbers though!

Man, get rid of that pacesetter y or weld a flowmaster y in it. Them pacesetter y's are funky.

I would get 1 7/8 headers and a better flowing ypipe (keep your catback) with a 25% UD pulley and dyno it on a dynojet and leave it be.... Don't go to crazy bc they you will hate the car

yes i think its your exhaust from the headers all the way back man..

JUSTINSWS6

My 429 ls3 made 674 to the motor. Its on 10.5 to 1 compression ls9 lingenfleter heads .630 cam fast 102/102 would make close to 600 rwhp

I was saying stock displacement LS3 not a stroker.

Maybe a new y-pipe and a cutout. I picked up 12hp with my cutout open. I also have a bullet style muffler right after my y-pipe and before my cut-out.

Nice numbers.

JUSTINSWS6

O. I know you cam you just have to have the right set up. You can get 503 rwhp out of a ls1. Mamo did it.

canada4g63

Run cut outs rite off the back off your headers, i would get some 1 7/8 though.

The Fast LS3 intake is not worth the $$!

If any exhaust change up. I personally would go with stepped headers 13/4 to 17/8 tjeb look into tsp true duals . The paceatter y pipe known to be not good merge and there is power and torque being held back there. Looks like a strong setup congrats!

My 402 with the same setup (11.5:1 402 and CNC LS3 heads) but with a 244/256 cam on a 114 lsa and 1 7/8 ARH headers and 3" tsp true duals put down 554/510 (dynojet numbers)

bigger headers for sure. then add that f1-a to it..and lower that CR, and run some good gas. that will turn into 900+ real quick with the right fuel.
