IF you were still using the original bigass starter, you'd need a 9-tooth starter drive. Since the mini-starter is a completely different design, you use whatever they come with, which happens to be an 11-tooth starter drive. Yes, a Chevy V8 starter for a 153 tooth flywheel is the SAME as for a Buick. The Chevy starter for a 168-tooth flywheel is NOT the same as the Buick. Some aftermarket starters fit both flywheels due to having two sets of mounting holes in the starter housing. If you used the correct mounting holes, those starters should work.
I just installed a mini starter on my 455, while it was on the engine stand, so I could adj gear depth/ engagement. I found for proper tooth contact, I had to mill the starter head. close to .030, to get good tooth contact,
yes I did, tried more than one shim, just could not get good engagement, best I could get, was still not sufficient tooth contact. nice part was engine was on the stand, upside down , used a 5/8 open end wrench to hold the drive gear out, to adjust,

I also run a Powermaster on my 13.5:1 555cui motor and that bad boy will crank that engine over all day long. I also run a meziere billet flex plate that Jeff Strube sells. Perfect alignment as I was having major issues
Not that I notice. They certainly crank faster than a heat-soaked standard one. They may actually crank a tad faster due to being able to spin faster for the gear reduction.
I'd think they'd crank at nearly the same rpm as a stock starter. The sound of fast rpm they make is from the gear reduction in the starter, the armature is smaller and spins faster than a stock type, but doesnt make enough torque to spin the engine, so it uses gear reduction, 4 to 1 is pretty common. The advantage to "mini" or gear reduction starters is their smaller size and less, WAAAAAAY less weight. You could make a stock type starter "gear reduction" I suppose, but it would be huge, and much heavier, and would be a torque beast.
So went to the site you posted and entered what vehicles it fits and it says 70 Buick 455 "Does not fit this vehicle"...so what's that all about?
By the technical application it doesn't,..but in the real world it does,...I actually prefer the 94 to 96 Corvette starter,..it's even more installation friendly
I assure you with everything in the world it will bolt up and function as intended,...with less weight,..more cranking power,...and no heat soak
Just look up a 95 Vette on rockauto, https://www.rockauto.com/en/catalog...+v8+ohv,1041376,electrical,starter+motor,4152
