well I'm going for it- I mocked up the older block with newer heads, the thinner gaskets of the newer motor, all the timing and ran the motor around by hand and everything clears! I am sure that I will fall back on CP: the phase 2 motor was listed 142hp with the older one at 130hp. My guess is that I'll be somewhere around 8.8 to 1-9.4 to 1 CP and probably around the 130hp mark. no biggy though as all it will cost me is the new gasket set! also for 70 bucks I found a G-force power chip, adds 60 hp plenty of torque and increases mileage 3-6 miles. That should suffice!
