Spare, On my 3.7 180 hp you had mentioned the Pertronix conversion . I am looking to pick one up this week,do you think i should go with the coil as well ? And does anyone know how Wellcraft fastened the gas tank hatch, was it with countersinking the screw heads or did they use s s washers. Thanks,

Don't know about the hatch, but I did do the Pertronics conversion a couple years ago. Its probably tha single best upgrade I did. I bought the Flamethrower coil with the module. It made alot of difference in starting and response time.

Mine had ss finish washers when I got it from the po. It doesn't appear to ever have had countersunk screws.

you might as well go with the coil while you're at it. Cut the tape off the engine harness and follow the purple wire back in the harness till you find the resister, its usually a hard wire u shape with black heat shrink, cut the wire above the resistor to eliminate it, replace with new purple wire and run it to the coil

Might try Car Shop Inc. I just ordered the Pertronix 2 ignitor and coil from them today as they seemed to have pretty good prices on these. My 470 already had the ignitor but a regular coil. Wanted to upgrade to the "2" and use larger plug wires and plug gaps.
