My 27ford coupe build started out with the old nasty firewall in place. when I ordered my 350sbc engine I also ordered the hei coil and of course it would not fit...so I returned it and bought a pertronix flamethrower and coil....I quickly started to dislike the old firewall and built a new flat one. question...what would be the better choice..go with the hei or go with what I now have, keeping in mind this is a carbed motor.
i'd ditch the hei and go with the smaller distibutor. both would work fine for you , the petronix just looks better
