Convert Proform ignition to Pertronix?

Giles,
The Carter pump is NOT a stupid design! Your 'failure' is only the second one I have heard of since it's 1969 intro. The fuel circulating through the elec motor is a brilliant design as it lubes the brgs, keeps the pump cool & eliminates a seal [ which Holleys have & cause failures ]. Any device that requires lubrication & is run without lubrication is going to fail, not the fault of the device!! The other failure I heard about....well lets just say I have my doubts that it was the pump itself that was at fault. I DO know of one Carter elec pump that was removed after 19 yrs of service; not because it failed, but because the owner thought it had earned it's 'retirement': and it was a daily driver!! These are the most reliable out of tank pumps ever made for carbed engines. If you mount the pump too high above the tank, the pump may not pull the fuel. Good idea to prime the pump on the bench before mounting. Dribble some oil into the inlet side of the pump; then run it for a few seconds.

With ANY elec pump, you should have a safety oil pressure switch in the oil pressure cct. If the car has an idiot light, you can use that to trigger the pump. If you have an oil pressure [ OP ] gauge, you can fit a Tee piece & fit the switch to the Tee.
How it works: If you are in an accident & the engine stalls, OP goes to zero & stops the pump pumping fuel. For easy starting, a little bypass sw under the dash allows you to power up the pump to start the engine.

Back to ign.
The HEI I described is the best way to go for a number of reasons. More compact, less wiring. HEI has adaptive [ variable ] dwell. The Chrys ECU does not. To avoid misfires at higher rpms, the C ECU increases the dwell period. The coil is charging [ current flowing ] during dwell. At idle & low speeds, dwell does not need to be high....but it is......because it is fixed. Result is that the coil gets hot. Not good in an already hot engine bay.
HEI has adaptive dwell; dwell is reduced at lower rpms for cooler coil running. Also, to get the best out of HEI you should use an E core coil that does not use a ballast res. The MSD # 8207 is cheap & excellent. Also, Bosch had a GT40 E core coil that is very good, maybe available in the UK.
You can open your plug gaps to 0.060" with the extra spark energy of the HEI.

Congrats on the Edel carb, a good choice.
