What size of a battery (CCA/CA) should a '73 350 engine take? I'm beginning to think my battery is too small and that is why I am having starting issues.

Thanks in advance

I would look at AC Delco battery 78-6YR. Should fit in your car and it has 700cca which should be enough to spin that engine over.

However! Your starting issues may also be.......your starter. I just replaced the 25 year old starter in my truck this weekend. It was cranking like it was -25 out and it didn't seem like the battery had juice. I put in a new starter though because of how I treated it this winter and you would not believe the difference. It spins over very fast and fires right up.

Lastly, have you ever checked your charging system?

I was told by a female parts counter clerk once that size matters (I hope she was referring to the battery I was buying at the time) ...
I just kept telling myself she was talking about CCA's (cold cranking amps)
