    electronic ignition 3.7 lx (470)

    FWIW....I have had 100% of the pertronix kits I ever bought fail. I have never been stranded by a set of points. however prior to ripping anything out, simply ground and unground the coil repeatedly and every time you unground, the coil should fire.

    VP 5.0 to 5.7 high idle

    running the 5.7 on a 5.0 calibration means the motor will be running lean. even with the electric toilet on top (TBI) make sure the throttle cables are not holding the throttle open.

    your crank and pistons are the same, you dont need to change them. you are only changing the heads and intake your cam and block is fine you may need to go up in prop pitch, however wait until you get the boat back on the water.
