5.2 magnum options

i dumped the msd box, I have a re-man dist. and the GM 4 pin module ( petronix version ). never thought about it being bad, I have a stock 4 pin module and different dist. I can swap in. I will give all the wires a good look over as well.
maybe I will even just run a temp. hot wire from the battery to the ignition just to rule that out.
Magnum, do you have a suggestion for a cam upgrade in the 318?

Sure, I have lots of upgrades, do you want to use stock springs or go to larger springs. If you use stock springs you will have to keep lift under .475", our stage II spring kit is same as Hughes and will work up to about .550" lift.

GM HEI module could easily be problem. Rotor phasing is more for MSD distributors running FITech FI system or serious racing, not really needed with a street engine. Pull cap and roll engine up to TDC. Rotor should be pretty close to lining up with #1 post, depending on initial timing.
