Many have converted a points distributor over to a HEI with a kit and not had any problems. You have to remember, in your case when you can stuff a HEI in there but the fit is tight, if the engine jumps in any way it`ll break the distributor cap. A used to be friend of mine had a 72 Nova he installed a HEI in, the cap was hitting the fire wall, his solution? he took the hood off, marked the spot on the firewall, stood on the cowling and hit it with a sledge hammer. The only down side to converting the points distributor over is the terminals are alot closer together so you have to make sure you get your rotor pointing at the correct teminal. Closer together also means arcing inside the cap can occur, so make sure you use a top quality cap, rotor, and use spiral core spark plug wires.

when fitting the engine in this truck. i did massage it a Little with a bfh. to the tune of 3 inch's. the cap has some clearance, but i have one wire that rubs. so I'm thing one good romp in the mud getting on and off the gas might bring it against the fire Wall. the pints dizzys are just so much smaller.

Dist cap clearance

Why not use the point type small cap distributor and install a Pertronix conversion. I have used them in many applications where the original distributor appearance was desired, (old corvettes) and they work great.

Conversion

I don't think they are as good as an HEI, but they do work better than points.

You really will benefit from the stronger ignition of having elecronics in there. A points distributor can be up graded to electronic or optical switching with a kit.

I have use the petronix in several different rides and only burned out one set and it was my fault. Cheap and easy fix install in about 5 min or so just don't go and leave your ignition switch on it will burn them up. But myself i really like the kit. i would use it again if needed . JMO
