LS3 and Hot Cam Results My dad had his A4 GTO with a crate LS3 and GM Hot Cam on the dyno this weekend.
Car has a CAI, P&P Throttle Body, 25% Underdrive Pulley, Stainless Works Longtubes and X pipe and an aluminum driveshaft.
Car is on a stock stall for the time being.
Cam specs are:
Camshaft Duration @ 0.050 in. I/E: 219 / 228
Camshaft Lift (in.) I/E: 0.525 / 0.525
Lobe Seperation Angle: 112
The car made 434rwhp@5700 and 429rwtq@4750.
The motor still has a little bit of breaking in to do.

You might have taken my comment incorrect. I actually support the OP's cam choice. Its pretty amazing what the ls3 can put down with a few boltons and a baby cam. The OP will be enjoying this big number mild combo for a long time. Won't have to worry about valve springs and other issues that come with running a big cam. Good job bro (TO the OP)

It's actually my dad's car. The original LS2 broke a piston and cracked the block. His wife wouldn't let him go with anything that wouldn't be warrantied after the original was voided, and after talking to the GM dealers locally, they agreed to warranty a crate LS3 even with the cam. I agree though, it could use more cam.

More cam more cam. BS !! It must be awesome to have 443 rwhp at your disposal without the issues of most 443 rwhp motors. 443 rwhp with the reliability/durability of a stock ls3 !! Just enjoy and don't do anything else to it.

It's the GMPP 376/480 - right from GM that way.

I think the grand total was around $6000. Have to do little things like adapting the map sensor harness, getting the LPE 58x-24x box(Which was a real pain. Turns out his GTO was originally manufactured to be a holden model, and was changed over to a GTO while still in Australia. Evidently the cam and crank wiring are different, but LPE diagnosed it over the phone and sent a new box and it fired up fine.) It sounds very nice as well. There's no mistaking that it's cammed.

Just in case you uys didn't know ANYTHING purchased and installed through the dealer (gm performance parts) is warrented....but THEY have to install it, if you order it and have someone else other than the dealer install it then it is not warranted unless its a crate motor which comes with a 3/36,000..but everything else that is purchased is warranted..just make sure tat your dealer is clear on everything....nice numbers by the way OP, I bet you and your dad will surprise alot of unsuspecting people when you pll next to them with a stockish idle and pull away effortless!!
