Default 72 Vette Cranking issues

Hey folks! Glad I found this site. I did some searching before I posted but I couldn't find a thread with the same problem.

A friend of mine recently purchased a 72 Vette that had been stored for almost 20 years. After some wiring, lubrication, carb, etc we got her fired up and running well. Just having one issue....

She will only crank if we jump start. Brand new battery, new engine harness, good voltages at the starter, neutral safety switch is good... I'm at a loss. The only idea I have left is a bad ground in there somewhere.

My buddy is handy, but hasn't done a lot of vehicle work, so i'm basically his go to guy in getting this car on the road. Anyone have any advice with what I should check, how to check it, etc?

I'm lost and need your sage advice! Thank you gents!

Check the ground connection under the battery compartment and pull the starter and have it bench tested.

I will certainly check the ground cable this afternoon, that was my next thought. I had the starter bench tested already, it's good to go. Thanks for your help!!

Where do you attach the cables when you jump start it?

On the Vette I go straight to the battery terminals, on the Acadia doing the jumping it has specific jump start terminals located near the battery box.

The only connections you are bypassing is the ones at the battery. There's something wrong there. Either the cable terminals are dirty or they need to be replaced.
