I am open to suggestions on what to build. I have a 03' LS1 with 243 head. I am looking for 400-450 HP with a Carb set-up. I wont be drag racing it, just cruising etc. Cam, intake, carb help would be great. BTW going with 700R tranny.

Building my own headers. I would like to use the 243 heads if possible. They flow the best out of the stock LS heads from what I have read.

I would assume that the stock motor puts out 350HP. All add a cam,intake, and carb and should have enough HP?

Your 03 ls1 has a ls6 intake so unless you want to drop 2k on the fast setup, the ls6 is your best bet. A 23x/23x 59x/59x 110-112lsa cam would make very good power. You could also send the 243 heads out to be ported too. Are you talking crank or rear wheel hp?

Edit: never mind the intake If your going carb.

If you go with a "smaller" cam since your just going to drive it around. You will need more than a cam. Even a MS4, t-rex, etc would gain but what 40-45 rwhp Most likely going to have to get some good heads. The AFR heads are pretty nice.

I read that a carb/intake will put out more raw HP?

A few more hp up top, but low end is effected and FI is the way to go if your just going to drive it around.
