Big Bore 3.2 to 3.8

[Jake Raby]

we have several different cam grinds available, dependant upon your application and inended power band and rev range.

What must be established first is what you will be doing with the engine. Is it a torque beast or a high revver? What are you willing to do to the heads? What ECU manipulation are you willing to do? drive-ability comncerns?

Here we have no generic parts, everything is application specific.

3.6 with the IA supercharger running 4.5-5 lbs of boost. I only drive the car for fun on and off the track and it has never been nor will ever be a DD. I am willing to do the valve springs and the cams while the motor is out and my guy is willing to flow the heads but said more then likely not needed. I know that the 3.8 X51 has larger valves thus the guides would need to be increased but again my tech said it is not really needed. I already have the AASCO ligt weight flywheel for it and the tuning like my current package will be a one off. The current tune was done by Garret of GIAC. Stephen Kasper of IA will have the next one done. I am looking 400+ or - on pump of reliable HP.

I am being told that I can continue to run my 7.2 system with the 7.8 motor through the magic of tuning, but I am not holding my breath on that one.
