The one with the S and R terminal? That's the Harfon starter. I was going to just switch solenoids but they don't seem to be removable
I've found that if you don't have the long bolt on the back of the case, you can install and remove (a normal sized starter) without removing the trans inspection cover. I'm not sure the size difference with the mini starter as I've never had one but the long bolt is a pain in the ass IMO.
Which ever one has the ribs on the cone for added strength. That was what I looked for in the one I used. If you are running points or using the stock resistor wire for the ignition, you may want to use the one with the S and R terminals, ribs or no ribs.
I'd use one for the first week, and after it craps out, use the other one for the next couple of days, until the RobbMc arrives. You should only have to borrow the wife's car a couple of times...
There's good things about each starter and it's a shame they can't all be on one starter. I expected the Delco Remy starter to be superior but.....
Yeah that “REMY” gives us that remember Delco/Remy a warm and fuzzy feeling I did break a nose on a mini starter I bought from a vendor on Turbo Buick years ago, but I had locked out timing. We were leaving for the nationals that morning, on went the 90 pound stocker, the hard cranking and kick back didn’t bother it. I’ve since gone back to conventional timing, but now have 11 to 1 compression, I have another mini on there from B&D, been working good.
LOLOL It’s some electrical place on the computer, who knows might be Black and Decker, or is it Ryobi now????
The big Nail has an actual (as opposed to theoretical) 10.25:1 compression ratio. Tom Telesco's mini starter has no trouble with 431 inches of that. BTW: I bought the mini for mucho less weight, there was no clearance problem. The Nail fits the Chevy Pickup better then the original 6.2 Diesel did.
