Mini Starter...Are You Happy With Yours?
 
Tryin to uninstall/install an Original 40/50 lb Delco starter around exhaust pipes on your back is not an easy task...

Anybody had any luck with a "Mini" Starter?
Yeah, and I got the off set bolt to block starter with the purple and yellow wire (points) solenoid...

Have one on all of my "not modern" vehicles including my 1946 CJ2A 4 cylinder Jeep...not that it's hard starting it's just that these things are bullet proof reliable.
Everybody used to make fun of the Crysler gear reduction starter whine back in the day, but those where proven to be the most reliable.

I put on a Proform Starter Motor (#66256) on my 70 when the original went out. It was a super pain getting out original with full length headers. I used this one as it was one I had from my prior truck's build. Starter has been on this truck almost 4 years, plus year or 2 on last truck. Does great Lot easier to get in especially since I went to shorter headers.

My mini starter is a Hitachi from a local speed shop. It's been in there for 12 or so years. Works like a champ!

A factory gear reduction starter from like a 4.3L S-10 works great and is available at your local parts store. I have one on my Blueprint 427 SBC and it has worked flawlessly.

I've used them in every Chevrolet I've needed to put a starter in with no issues at all. The only thing that I'd recommend, is don't "long-crank" them, they heat up fairly quickly.

I have a Powermaster 9612 that I installed a few years ago. It has worked fine, and it has no problem clearing my headers. One minor issue I ran into with it was that it sat too far away from the flexplate, so I had to machine about .020" off of it where it sits against the engine block to get the teeth to mesh properly.

Yeah, a Powermaster *seems* to be a better quality starter than a Proform, nowadays that ain't saying much really. A 9012 Powermaster would need a little more fiddling to work for me though (I have Points) and shimming/machining seems to be more of an occurrence than a Proform. Also Powermaster does have a (.1) better Review Star than Proform...
A Powermaster and the extra resistor wiring I would need for a 9012 to work for me is ~ $100 more than the (hopefully) a plug and play Proform.

*Side note...that will upset some, I do have a 50lbs working 1968 Delco-Remy Starter with a new Duralast solenoid on it, but Man it's Killer installing it!

I'm headed to Summit to buy the Proform right now, Hopefully I'm not back here in 3 months complaining that it pooped out on me......

You can use the Chevrolet, for example, a 1998 C1500 starter, and get the same one, just add Dorman bolts p/n# 678-107.

Yep, I see that, another guy in this thread mentioned that for a 6 cylinder S10, I think it's the same one or a variation. Delco on Rockauto about the same price OTD as a ProForm and the Delco is ~6 pounds heavier...

Ok, so I ordered the Proform Mini Starter I pictured above.

I haven't really dove into this yet, thought I'd ask Here First...
What About The Starters Front Hold Down Bracket?
My Truck didn't have one when I got it, the mounting hole on my small block and a pieces of all thread off the original starter are there but no bracket...

I will be checking into that.....

Re: Mini Starter...Are You Happy With Yours?
 
Holy Moly...Summit, Speedway and A1 are selling those Starter Brackets for $70+!
I ordered 1 from AutoZone $13.51 OTD....Hope I get it!


*Edit: ....Hope it fits... but yeah, I'll probably end up having to Blacksmith me a bracket out on the sidewalk with a piece of angle iron, hammer and a Benzomatic with my luck anyway.....

Re: Mini Starter...Are You Happy With Yours?
 
My mini starter failed after about 15 years. The front drive wore out. It is a 10:1 compression engine. I bought a stock unit and it is working fine for about 8 years. I made it so that both batteries are hooked up to it when I start and then they separate again. I found a drive for the mini and replaced it and now it sits in a box somewhere. It not the type you picture above. It's a CVS or something. The drive just hangs out with no support on the other side. It's a clockable unit. Worked awesome til it didn't.

What is the part number for the bracket, if you don't mind?

They are different starters. I know a guy that only uses the 6 cylinder S10's over C1500's. I believe the S10 starter is smaller, has more torque, and it's maybe cheaper. I think it depends on the source. I personally will be doing an S10 starter when I have to replace my GMC's starter

So far great. If I ever see another 10K pound starter again it will be too soon.

Here put this into Google and shop around you'll see what I was talking about.

GM Genuine Parts Starter Bracket 03965589


All the "Build" videos I've seen online never show *this Bracket", I just happened across it in a Venders Parts Drawing.

Yes, and I was told about some "points delete" gizmo that'll fit inside my 1968 distributer. I haven't shopped for it yet, if it even exists. And I know, I know I need to study HEI!

I had a '69 Nova (wish I still did, nowadays) with 250 CI six and ran points. I got as much as 33k miles out of a tune up. Almost all highway miles.

I highly recommend a 1990s AC Delco permanent magnet starter. All kinds of room around the starter. And the engine spins over faster than my old full-size starter.

It's an AC Delco Gold part to fit 350s (and maybe other engines) with 168-tooth flexplate/flywheel. Everything about mine looked brand new, as you can see in the photo.

AC Delco #336-1910A
GM #88864291

I paid $102 for it in 2022 on Amazon. Unfortunately it's now $148, but that's with free Prime delivery. Wish my income would have gone up 45% in the last 4 years!

Instructions are very informative. They call out specific bolt P/Ns you will need to use, which are knurled above the threads, unlike standard bolts.

By the time you changed to that smaller starter had you ditched your points?

Yes. Good point though. No pun intended!
