Calming Down a 6v Starter on 12v?

On my Avatar 2N tractor with 8BA I started with a factory 6V starter used at 12V. It did seem to hit a little hard so I bought a '63 390 Thunderbird starter that was 12V to begin with and used the flathead armature and drive in the Thunderbird case. It worked like a charm.

Then I put the engine in another tractor (8N) and bought a Powermaster mini-starter so I did not have to cut the transmission case/bellhousing on the tractor. They are kind of nice but definitely not period correct looking.

That's a nice write-up on that V8 conversion. One of those potential projects which I try to suppress the urge for. Yours really looks great.
 
I hope those cradles under the 8BA are pretty stout. The N, NAA, and 600/800 series use the engine block with a heavy pressed steel front mount for the front axle attachment. I've had to weld those front mounts up due to cracks before. That cradle that ties the trans to the front end will have to be pretty heavy duty to take the bump and grind of field operations. If a person just plows a nice flat field or drives it for show then it may be OK.

I can't speak for the Redrock version because I have not seen one in person, but the Awesome Henry one is very stout-and heavy. I have never heard of any complaints with breaking on either one. I really like the design of the RR version because it would allow a wider radiator and mechanical fan. I would like to see one up close so I could study it.
