Hi all, I have a 75 TA with a standard low comp 400 with headers only. I started having hot start issues a while back and have done the following:
-wrapped the headers near the starter
-put a metal heat shield over the headers
-wrapped the starter with a versa shield and then a metal heat shield over the top
-new 4g starter wire
-new optima yellow top 34 battery
-new battery terminals
-0g ground from battery to original ground point at top of hearder
-extra ground from battery to other side of motor

I spent all day today redoing the wiring for the battery and it still cranks like it's dead when it gets hot. After I let it sit for 2.5 hours or so it cranked and started perfectly.

I don't know how old the starter is, but it has been replaced at some point. I've checked the timing and that is fine. It doesn't run overly hot either. My only thoughts at this point are to move the ground somewhere else on the engine and/or a mini starter.

Is there anything else anyone can suggest? Thanks in advance.
