LS1 Head/Cam
I'm looking to build an LS1 in a 2003 C5 M6. Considering AFR 205s, Comp 224/228 113LSA and LTs. Would that likely get me 410-420rwhp? Any suggestions. Thanks.

Thanks for the advice guys. I was thinking of doing slightly more on the cam but didn't know which one to go with. I'm going to take the advice here and call Tony. Would the G5X3 be a step up from the 224/228? Will I need to do an intake and/or an aftermarket TB. These probably seem like dumb questions but I haven't done a motor in a long time.

Yupper the G5X3 cam is a step (or 4) above the 224/228 cam. Actually I am installing a G5X3 and a set of 205-AFRs tomorrow for a friend.If you have a LS6 intake stick with it. Get a ported TB if you do not have one. Get an UD pulley if you don't that. Once again call Tony at AFR. I am sure you will hit your goal with the package he recommends... probably somethign like 61 or 62cc chamber size and his 224/228 cam.

Yea the G5X3 is a pretty big cam...WIth a good tune it will be fine on the street but without a good tune it'll be like trying to drive a race car--not good in stop and go traffic.
I'm planning to go with either the F13 or G5X3 (or maybe G5X4, we'll see) and AFR205's pretty soon.

Yes, I’m using the TPIS headers. As you said; they did the job for me. I’ve have them for a while (pre heads and cam). I think there are better options on the market now as far as headers are concerned. I’m running the Random Tech cats and an X pipe.
I think you will also need to upgrade the stock clutch if you haven’t already done so. 410 gears are also highly recommended.
Good luck. PM me if you have any specific questions.
