Twin Turbo Ls3

[v502]

I looked at the LSX376, but passed on it. I figured with the LS3 heads and cam it comes with, limits its output for $6K. You would need to change the cam and do head work if you want to up it above 700hp flywheel. Then I wondered about the GM powdered metal rods used. pt#12607475. Then I worried about the LS3 heads under 800hp boost. Then I figured, do I really need an LSX block for 800hp? Then changing the cam would void warranty because GM probably knows it shouldn't go higher in HP..

SO! I just ordered an LQ9 370cu/in short block from Texas Speed.. $3200

I'm thinking I will put on a set of AFR215 heads and a cam that works nice for the street--easy 800hp with no questions about strength. This is with 10psig boost and 8.7:1cr non intercooled

I agree with you on powdered metal rods they sound suspicious and with my style of driving i don't think it will last.




You can call me the Terminator when it comes with driving my cars.
