High Torque Mini Starters

[D.PASSMORE]

My stock starter is going out and I would like to try something different, so I was researching mini starters, came across this guy:

Powermaster Ultra Torque Starters 9400

https://www.summitracing.com/parts/pwm-9400

I know its a powerful starter for a Gen 1 / 350 running 9.87 compression. Its a mini made out of aluminum, with adjustable mount plate. I need the adjustable mount plate because I'm running a SM465 with stock bell housing.

My issue with stock High torque starters is when they heat up, they dragggg. I have done all the suggested fixes, starter wrapped in thermal tape, aluminum heat shield, new H/D battery cables wrapped in thermal tape. Running Oddessy battery (always)...

Blazer has been sitting for a few weeks, went to start it yesterday, starter dragged a little, thought it might be battery, ran it for a while, check voltage, good, ran for about 10 miles down the road. Came back, shut if off restart, barley turn over, put big battery charger on it, no effect, drag and would not fire. Battery is good under load test. Seems like when it heats up, it dies. Went out this morning, fired up no problem. So, just looking at different options and opinions.

Thanks
