I dont know guys. Forced induction definitely has the sky as the limit. I'm just not sure if I want the added complexity, weight, added risk of heat soak, and added maintenance of forced induction since I am not trying to reach the sky. I got a quote from Texas speed for those heads and they are the heads on their SBE LS1 record car. I know they are good but at almost $3k it has made me want to look at other avenues before spending that much on just heads. Any other head ideas?
Also for now I think I am going to do larger headers (1-3/4 to 1-7/8), 104 mm Lid, and 100mm MAF just to get the ball rolling.
I haven't ruled out FI but, for me, i'm not sure.

You could keep it simple and just add 8 psi of boost to your engine just the way it is, and make more power that you can with a streetable heads and cam package. Bob

At some point, the increased flow numbers will stop helping horsepower and start hurting torque.
You could gain 90% of the power of those PRC 227cc heads with heads that are half the price, and probably have more torque.

Don't know if I'm too late, but I just went thru this ('02 with the stock LS 6 intake/TB and got 404 RWHP...
If I had to do it over, I would do the Pro Charger, and be done with it!
Second choice, all be it a bit more expensive, would be a 525 HP, LS 3, crate motor and enjoy the rush...my '12 Grand Sport continues to amaze me every time I drive it...

With a better job now and things falling in place, I am still not sure I would want to just throw this motor away as it runs very well! It dyno'd at 413 RWHP (burning oil from crap valve seals and Header Leak) but it traps 119 in the 1/4. All that is done to it is a cam, Small SLP lid, Small 1-3/4 headers, and Loudmouth catback. So the motor is still fairly stock. I feel like it has a lot of potential left in the heads and intake. One vendor is pretty confident that a FAST 102 and some C&C'd 227's will have me kissing 480-500rwhp with the same cam.
I am still undecided as I would love boost but just not everything that comes with it. We will see I am still carefully considering.

Only thing stopping me and more than likely most guys from going with a procharger or turbo is the cost....
I would much rather have a mild street able daily driver with forced induction 500 rwhp than a huge peaky N/A setup at 430-470 rwhp.
I have a small cam setup, I went this route because I decided if I wanted to boost my car I could and not have to change a thing.

You can make 430-470whp with a 346 NA and have nice flat power curve if you spend the money on quality heads and keep the cam reasonably sized. Most want to go cheap on the heads and throw the biggest cam you can fit and end up with a setup that sucks to drive.
