Looking for distributor advice

So the project took a (somewhat) unexpected/unwanted detour yesterday. Not wanting to crack open the 350 from a 1972 Impala that was in my truck, I was was finally at the point of no return. Time to open her up. My neighbors dad is in town due to a severely ill relative and needed a distraction. He is a big gearhead so he has been walking over quite a bit to see what I have going on. I gave a wrench and boy did we have that thing apart in say 10 mins?

Anyhow, the engine has a BAD cylinder, needs head work, a couple other cylinder were questionable so I said screw it and ordered a GM crate 350. Just their basic entry level one. I am going to need a new distributor for it. So putting out for masses and want to see what you would order up for it. Am I a glutton for punishment, yes, but I am really thinking I want to stay with the small cap style and not the large cap HEI. But I want your honest opinions. This motor is basic and will be run with ram horns, an Edelbrock Performer and 1406 carb as I have that already. It’s a daily around town driver on my days off and run to the local drive in car shows. And it’s going to be backed by it’s 3OTT. Thanks for the info in advance.

Can't tell you what to do, but happy to tell you what I did. After changing points & condenser a few times in my K20, on my belly atop the engine, I installed a used GM HEI in 1980. Best thing I ever did for my truck (and for me).

Re: Looking for distributor advice

I highly recommend getting an early cast iron distributor. The early units have larger and better quality bushings giving you accurate spark distribution equal to the best units on the market today. Plus you can keep your small cap!
After cleaning and verifying the bushings are good install the basic Pertronix point replacement module. Solid units that I have run in various vehicles over the years with no failures.
For best performance (both HP and mileage) have the distributor curved by someone who is experienced with a distributor machine.
And just in case I carry a set of points and the screws to get me home if any thing did go wrong. This is the one for my Burban in the photos.

Re: Looking for distributor advice

There's a variety of small cap/external coil H.E.I. distributors out there. Speedway sells one for under $70. Awhile back we replaced the tach. drive points distributor on a friend's '64 Corvette with a small cap H.E.I. tach. drive. Bought the stock looking one w/black cap & wires. The car starts & runs much better.

With the small cap style, does this necessitate the elimination of the resistor wire and adding a regular wire for full voltage like a regular HEI?
