Gosh, Deve,

If you are interested in best cost, stay with points/condenser.

If you want HEI at the lowest cost, make your own (Jason).

If you want to know about fuel economy, it would be nice to know if anyone has good enough data to calculate how many miles you have to run to payback for Pertronix/HEI/Jason-option.

It will be interesting to see if anyone has data to compare performance of HEI vs Pertronix vs Jason-option?

The vacuum advance works with on a Pertronix the same as with points.

However you decide to go, carry a spare or a backup.

HEI gives you glam; but, points give you the ability to explain to a young person how it was done in the old days.
