Small block mini starter
I agree with 66PlyValiant. They come on all rear wheel drive V6 and V8 from at least the early 90s. I have encountered one situation where the mini starter would not clear something on a block casting but run them on all of my 318, 340 and 360 combos currently in service love them and much easier to install with or without headers. You might have to modify the wiring connectors slightly on some but easy fix and very worth it.
