If I were you

I would call one of the larger mfgrs. of mini starters and see what they say. I have rebuilt starters for a living for over 20 yrs. and can tell you that theres usually nothing special about the bendix or drive gears between the conventional, heavy duty, mini or OEM starters. Its all about the motors, and if applicable the gear reduction. I am thinking that with the correct info you can put a higher kilowatt motor on your starter pretty easily. But you would need to know which one to use. Like I mentioned, pick one of the many reputable companies offering the mini starters today and talk with someone in their tech dept. Surely one of them is willing to help you out. If not, do you have a local automotive electrical rebuilder in your area ?
Hope this helps in someway !

starter mount.

MY SB chevy powered jeep used the starter that bolted to the belhousing. somewhere I read thaat that type was a 50's chevy bellhousing You might have to change to a later truck bell housing to use a block mounted starter if your engine has the provisions for a block mount. I have also heard that some other GM starters for Buick, Olds or Caddy have more starting torque. and fit the older bells. not positive on what will work.

:confused:
There are no bellhousing-mounted mini starters to the best of my knowledge.

That said, on some of the large bellhousings Chevy used behind some truck engines, there may be enough room (sometimes requires some grinding to get clearance) to mount a block-mounted mini starter. It will use the holes in the block (shown below), so if the block has those holes you might be able to use one. This will not work w/the smaller passenger car-type bellhousings, though.

NAPA lists PN 246-4803 "low torque / high temperature" for your 1972 Chev / GMC C1500 with 350 M/T


They also list PN 246-0717 "high torque / low temperature" for the same application with a 402 (big block)

Crossing them into Wilson ...
246-4803 => 91-01-3821
246-0717 => 91-01-3831


Both of the above Wilson #'s have the opposite #'s in their "can use" list, indicating that they should be interchangable with each other.
Sorry, no specs as to Kw ratings.

Update:
I thought perhaps I would check Wilson's B.O.M. (Bill Of Materials) for those 2 different numbers
91-01-3821
90-01-3831
The good news is that both starters use the SAME drive and drive end housing.
They also use different armatures and field coils ... so the "high torque / low torque" version theory seems entirely plausible!
Might be worth a shot?
