67 C20 with 283 w/3 speed on the floor keeps killing starters.

Quick update:

Went out to yank the starter and found the main power wire broken.

Had to pick up a replacement wire, since the existing wire is old, stiff, and covered in oil (intake leaks like a bastard) and I'll report back to see if that's the actual issue.

Even if it DOES solve the issue, I think I'm going to pull it to check for block mounting options to run a mini with a heat shield. (maybe I'll wrap the header, too)

Thanks for all the help, fellas!

Aaannnddd it wasn't the broken wire.

I've got a stock warranty replacement for now, but when this one dies, I'll step up to a new, smaller unit.

What a pain...

Are you saying you replaced the starter since your last broken battery cable post on the 8th? Did you see the three mounting holes in the block when you had the starter off?
Might as wwell put a heat shield on it now.... or
Go with a Powermaster and never look back. But I would still put a heat shield on the header, or, over the starter to protect the investment. Stuff ain't cheap.

I’ve always had problems with my 72every starter was too far away from the flexplate . I had been shimming the outside bolt to swing it into the ring gear . This time after putting in the new flexplate I decided to end it once and for all . I milled the mount on the starter and kept putting it in and checking my clearance. I got it to .025 without shims but I put a shim in to bring it to .030 . Powermaster calls for between .020 -.035

You could probably stick just about any old piece of metal between the exhaust and starter to make a heat shield, just bolt or clamp it on there or use baling wire to hold it in place. A coffee can treated with some BBQ high heat spray paint or exhaust manifold paint brushed on from a can so it lasts a few years would probably be pretty good. I made a heat shield for my Mazda Tribute and it worked great. Roof flashing also works great, it is particularly good because it's galvanized. If not abused the starter should last a very long time.
