jeremy, go turbo or go home. wouldnt it be nice to just turn the boost control up instead of having to change pullies. you also wouldnt have to worry about belt slippage either

also jeremy when it comes to FI you dont have to have HUGE motors in order to make good power, especially not w/ a street car in mind like yours.
standard bore is a 4.125 and a 4.00 stroke you'd be at a 427ci

I believe that the TSP drag C5 is a 4.125 bore or thereabouts.
I know in talking with Josh and Wormery at LMR they like a 4.030 bore so that you leave some room for the future if you need to take out the motor a bit more.
