Xena, couple options… There are aftermarket "small cap" HEI distributors for SBC made, that are close in size to the original distributor and cap, not like the huge GM OE HEI units. Search eBay or other for "small cap HEI."
Pertronix is an option as Tim (and others) have said - but if you go that route, look for their Ignitor II or Ignitor III, which are true electronic ignition sets, unlike the original Ignitor which just replaces the points, and consider one of their "matching" coils.
Also, since your stock distributor is very tired, and if you decide to go with Pertronix or stay with points, you may want to check eBay for the same distributor number as your current unit. If you can't find the number tag on the current distributor (which should circle the narrow portion of the distributor body just below the wider upper body), let us know the specifics of your engine - original model year, truck or passenger use and so on - and we can probably help ID what number should have been in that engine. Used SBC distributors are cheap, and with some searching, there are very good cores that show up all the time for about $40-45. May give you a better rebuild candidate, at least. Make sure you get a cast iron body distributor and not the later aluminum body, if that's what yours had, and you want to stay as close to OE as possible.
Anyway, some more things to consider... Happy Memorial Day/Weekend!
