If your tuner is as good as you say, I'll be low. Where do you find a good tuner in Germany anyway??

Your head/intake combo is leaving a lot on the table - predict closer to 500 rwhp with heads/intake switch.

As 420hp is taken, I guess 415hp =)

Idk about your time constraints but I just picked up a set of new LS3 from Summit for my LS3 build for $660 for the pair ($329.99ea) Actually thats Jegs price but Summit price matched it. Thats super cheap for the performance they deliver and compared to aftermarket LS1/2/6 heads.

I think 420rwhp is a safe guess for you since many stock LS3 with bigger cams than yours are around 450+hp. Im looking for maybe 480rwhp with a TSP 231/236 114lsa cam on stock heads and short block, plus all the bolt-ons and associated mods.

How to find a tuner? Ask around in car clubs.

I know, I know. I'm leaving alot of power on the table. But time/money/energy simply don't allow going Full Monty now.

Is that the price for complete heads with valves and springs? If so, yep, great price...

Yup, 100% complete. All I did was change the valve springs for the cam. You can see the heads in my sig pic.

How did it do?

I'm gonna say 417 to be different. But quite honestly I would ditch those POS 918's and run a dual spring for safety's sake. That's what took my original LS2 out the first year I had my cam in.
