So I am building a Fox, with T56 3:55 gears, straight 93 octane. I have long tubes but the engine is apart and will need some work. So I am trying to decide about having the engine rebuilt using block, rods, crank but upgrading pistons. Will definitely need the heads gone thru. Looking for 650 to the wheels, so what long block would you recommend? What supercharger? I have a stock ported Eaton,
