Slow Cranking
#1
My 72 351c has developed a very slow cranking problem over the past few months, I've got battery cables(8 gauge I think) that are less than 6 months old the positive wire gets so hot it could cook an egg, the starter is probably original, but I had it tested and it checked out, I replaced the battery with more cranking amps (935 to be exact) and starter cable,(4 gauge) as well as a battery to block to chassis ground, I'm flying through solenoids, they work well for the first 10 seconds of cranking then shit out and get hot and the motor barely turns over. I'm damn near ready to quit this car any and all recommendations are appreciated.

Assuming the engine is healthy, I would check the ground wires.
10 secs you say thats a long time to start a car...

I got nothing but issues with the original starter. From hot start issues, slow cranking, hot wires, brushes gone powder creating shorts... Once it starts probs never ends.

Save yourself headackes and spend little on this baby

Draws much less power, cranks twice as fast. Changed the game completly. You save 1/2 the original weight too.

It does look a bit bulk, will it work with long tube headers?
