Hello I have a 1999 ls1 that has an ls6 intake, headers, 80 injectors, boost a pump, p1 supercharger and the engine is otherwise stock, I'm currently making 530 rwhp with 10psi of boost, I would like to add a cam and heads that would get me to 700-750 rwhp with a stock bottom end and still be reliable and be driven daily on the street if that's possible, I know I'm going to get many opinions but look forward to hearing them all, thank you.

Any suggestions?

Use best parts and make sure that the tune is optimal as well.

Pulley down, put in a good cam, get a real fuel system. E85 or pump plus meth should get you in the 650-700 area. I wouldn't risk expensive heads on a 20 year old motor. Guys have made 750+ with the stock block and 241's. P1 is like a T trim or 1500 at 1200cfm if I remember correctly. Might take a bit more to spin though but you should still see 650-700.
