I currently have a TVS2300 that has the intake ported, LPE 69cc CNC heads with upgraded valve train, LPE GT-9 cam, L99 -LS3 conversion, RotFab CAI, Stainlessworks 1-7/8" headers and 3" exhaust. Not really related but for information purposes I also have an RPM Transmission 3.70 diff, DSS 1400 hp axles, Phadt diff bushings, subframe bushings, sway bars and inverted coilovers.
The car dyno's at 590rwhp and I am running a conservative 7lbs boost to preserve the stock bottom end, which leads me to my questions. I would like to stroke my motor and replace the rotating system with forged internals to be able to increase boost to10psi. My goal is to have a car who's application is about 60% track and 40% street.
My preference would be to stroke the 376ci. motor to 427ci. with ~10:1 compression.
Question #1
- Can I get 427ci. by leaving the bore stock and increasing piston stroke?
Question #2
- What would you recommend for crank, pistons, rings, etc?
Question #3
- I would like to get just slightly more aggressive with the cam, what could replace the GT-9 to accomplish this?
Question # Last
- Could I reuse the LPE 69cc heads or would I need the 73cc to have 10:1 compression?
Thanks, Bryan
