Hi! I have a 68 camaro with a 427 and 5 speed. I have had a hard time finding a starter that stays cool enough to start right after a trip. It has stock exhaust manifolds. Please send your recommendations for a good starter for me. I have attached photos of the last 2 I have tried.
If the best fix is to insulate the starter please send how you've done that too.
Thanks as always!

 

I used a heat shield wrap on my 93 lt1 starter. the headers are so close I just did it for piece of mind. easy install.

 

A half century ago, I built a SBC Vega with a 302 w/ 12.5/1 pistons, headers, and all the goodies. It would not start when hot due to the heat under the hood. Stock GM starter. I had to hit the kill switch and got the engine rolling with the starter, and then flip the switch on and it would start. The combination of drag on the starter due to heat and the initial timing advance would stall the starter.
If you pull the coil wire and the starter cranks / spins the engine when hot, you can do one of two things: Retard the timing (no fun at all) or put in a shield on the starter and a kill switch.
Give it a try.

 

In dirt track racing, All of our extremely high end, expensive, light weight, mini, reverse/bell housing -mount starts come with a pre wired jumper. We still do it this way for multiple reasons. It really hurts nothing and the remote solenoids are plenty capable of moving the 18v current and the necessary amperage required. We actually have instances where we start the car in gear rolling it with the starter like a push start with zero problems. When we start our 950+ Hp high compression engines they fire near instantly not like displayed in this video. The remote solenoids are fairly in expensive and can be swapped out instantly rather then the entire starter which is what fails even wired with out a jumper. In fact, they fail more that way.
