Mini starter
Any magnum 318 or 360 V8 in junkyard. Its a mini denso starter.
Your OEM big sized starter weighs about 16 lbs and comes in 2 flavors 1.6 hp, and 1.8 hp for big blocks.
The stock mopar mini denso only weighs about 8 lbs and puts out around 2.25 hp
What goes bad is the contactor on the back of the starter under the triangle cover w 3 screws. Repair kits for that are inexpensive and easy to install.
Just picked one up for my kids car at the junkyard off the tested shelf pulled from a ram van. $25. Bonus was under the grime on it was a rebuilt tag lol.
