71 496 w/headers - mini starter options
Starter died and time for a new one. 71 with 496, 10:1, Hedman headers. Of course heat is an issue. Dead starter had insulation wrap. First looked at Powermaster 3510 and buying heat shield. Now thinking mini starter might be way to go. Powermaster 9426 might be a good fit.

Hoping Milodon oil pan with kick out is not fitment issue. Would appreciate input from experience with similar set up.
Thanks

I had a horrible heat problem on mine with the hooker header long tube side pipes. Ended up wrapping the headers from the flange to just behind the tires. Made a huge difference in under hood heat. I would go that route as well.

I got one of these for my 496. Admittedly, it probably has plastic gears inside it, but it works great. And for the cost, I'm thinking it's worth it.

I've had a basic Summit mini-starter on my 555" for many years. It's a Nippondenso design and can be rotated to any position. I've got a turbo a few inches from it and no issues with heat soak (starter is not wrapped). The design is very good and if you need to repair it...parts are easily available....but not likely you'll ever need it.

I recommend this one.....had these on three Vettes and countless customer rides. Spins it like it has no plugs in it.

I use the Hitachi style (GM) mini starter, it is freakin tiny, has the full cone over the starter gear and works great on my 10-1 496, even with the timing locked out at 33*. Been on there for 20k Miles.
Its actually an O Reilys Ultima brand with lifetime warranty...never one issue.
i had tried 3 different mini starters and had problems with all 3 holding adjustment and hitting the gear on the flywheel. (Summit, TCI, Hamburger)... slapped on the O reilys with no shims, no clocking...nothing. Works fine. You do have to run the GM metric starter bolts, you can get them at any dealer.

I have had the higher model than Jebby. Not 1.9 hp but 3.5 or so
when I first installed it I messed with shims to get more teeth engagement. They told me that 75 % was plenty

I actually have the Autozone version and just had to get a free replacement after ten+ years.
The GM part # is 8000598 and the bolts are 12338064. Autozone part DLG9990S. 1995 Chevy truck (3/4 ton) with 7.4L.

I have the cheaper PowerMaster mini, it was about $130. '71 454 with headers. Starter is not wrapped. Works great, no problems, and I bumped compression to 10:1. One thing that made a huge difference in how it cranks was to replace the '71 battery cables with '72 cables. In '72 the battery cables are heavier gauge compared to earlier ones.

Another good upgrade. I actually replaced my battery cables (#2 gauge stock) with #1/0 gauge battery wire from West Marine. Nice and fat with very little voltage drop. Did the positive cable, all grounds, and added a terminal block near starter for the feed from my my 140Amp alternator (plus fans, MSD ignition, etc).Here is the info I posted before.
I spent like $80 to get the thicker cable at West Marine. It is made for boats and is nice and flexible. Made 4 cables and even used the tool at West Marine to crimp the terminals.
- Positive to new terminal block ~8 feet
- Terminal block to starter ~1 foot
- Negative to frame ~2.5 feet
- Engine to frame ~.5 foot
Used 1/0 gauge wire.

Thanks Jebby, CVR looks like great option. I always try to read the lowest rating of reviews and found common complaint with this one to be same as other starters makes in that it does not make full contact with ring gear. Guessing that something is wrong with the install rather than starters. Could you please educate me on where they are going wrong. Thanks again.
I removed the 25 lb. turd from my 82' C-20 454 that had all kinds of problems and bolted a CVR on it out of the box, no shims and it is the best sounding starter in the world.......sounds like it was made to turn the engine over.......
Another issue people have though is brand new starters with shoddy wiring.........this is no place to have crap wiring......many cars pull power from the starter area as well as the sheer amount of amps (150 or so) when the starter is engaged............
I like the CVR because it is a derivative of the Panasonic style motors and the mount plate is spot on and you can rotate the damn thing 360 degrees as well......quality stuff for $200.

I was planning to measure the gear clearance on the powermaster when I installed it, but my bell housing makes it very difficult. So I installed without shims and it worked perfectly. Very quiet.
