I use the CVR 5323. 5323r for points ignition........best starters out there for the money and have never had to shim a single one of the six I have installed.

These cars did this when new.......my all original 69' 427/400 did it......
Putting a CVR on there opens up a ton of room.....and shaves about 15 pounds. Win, win.

Make sure the battery and battery cables are in excellent condition. Heat raises resistance to electrical flow so you don't want to make it harder to start due to weakened battery and oxidized cables with poor connections. Similar comments also apply to the solenoid and its electrical connections -- degrease the contacts and make sure all of the wiring is securely attached. Secondly, or is this thirdly, there is a GM heat shield that mounts to the block, fitting between the solenoid and the exhaust pipe. These are all simple fixes that have worked to eliminate the hot start problems with my big blocks.

Agreed on all. I have this starter https://www.napaonline.com/en/p/NNE4...put=NNE+4N1601 which is more $$$ than Jebbys suggestion (I’d go with his)..but had hot start issues. Turns out I had a bad ground. Fixed the loose ground and all was good again. Started fine when cool, but hot...never. So good starter AND good ground is needed.

This is one area of a classic musclecar that should just be done upon ownership. Makes the vehicle much more reliable and user friendly........there are purists that would argue with this but I as an experienced wrench will never install a 20 lb. crap original starter on anything.....and after you remove the original and hold the 8 lb. unit up with one hand to thread the bolts in....you won't either.
Putting the heat shield on an original starter is fun too.....and leaves even less room in the area to work with....also covers the wires that power the whole car in the event of troubleshooting......
Another lesser known benefit is it draws less amps off the battery to start.......giving you an extra buffer if you have other issues that require cranking.
One of the best $200 you will spend on your classic car.
