Default Help with starter

I am working on my next to do item. I have a 71 454 car with a starter problem. The car starts fine cold. When it is hot it cranks, but to slow to start. I let it cool a couple of hours and it starts right up. I just finished installing a mid 90's GM truck starter on it, and it cranks to slow. So I put the old starter back on. Does anyone have any replacement starter suggestions, other than leaving the old one and installing a heat shield? As always thanks in advance for your help!!

I have the GM starter that they use on the trucks and the 502s and a lot of other things. Mine cranks like crazy hot or cold. You may have some other problems in the starting system. Make sure the battery and connections are good and check the ground wire from the motor to the frame.

If that GM truck starter is new return it for a diff one, if not it might just be bad, it should have enough ***** to crank the eng over unless it is not shimed properly and causing some binding when the starter is engaged.

Gordonm,

Do you know specifically which model/year/engine size truck your starter came from? The one I have came off of a friends shelf, and I don't know the particulars on it.

I think the part number is 9000852. Light weight GM performance starter. It is a gear reduction starter.

I had the same starter problem on my 73, started great when the engine was cold, once it got hot, the engine turned over very slowly. Replaced it with an AC Delco starter from the local parts store. Works GREAT, no more starting problems hot or cold. If I remember correctly the starter was only $29.99.

About fifteen years ago, I had a local auto electronic shop rebuild the original starter on my '71 LS-5. It still works great after all these years.

Put a higher cranking battery in it. If you already have a really good battery and it checks out completely, then check your charging system.
