....it should work great. I kinda did the opposite : 74 1 ton tow truck 350 4bbl 4 spd, pitched the point/cond and stuck in the HEI dist , just timed it 4 degress ( I think, it was long ago! ) and it works flawless. So it should be very good in your pontiac. I would reccomend a new set of spark plugs , even set to 045 if you bend the tip enough , as now you have a stronger spark with more fire so a better burn and might even see more mpg.
