Title: 1983 Chevy k10 With 454 Starter issue
Post by: Cdog_1996 on January 24, 2022, 08:04:51 pm

Need help!  I have a 454 out of a 78 suburban in my 83 k10, has started and ran before but my starter is very far out from the flex plate, the Bendix might catch 1/16 of an inch of the flex plate, turns slow, sometimes it doesn't do anything and virtually impossible to get it to crank consistently.  Makes a terrible screeching sound, I've tried a stock style and a mini starter both with the same issue, I can't find a solution for this problem

Wrong flex plate?

I don't think so, it was attached to a th400 and then pulled I installed it to a built th350, seems original I don't see why or how the flex plate would be wrong and it matches the pads on converter

Is the bendix fully extending (and at least 12v to the starter)?

Is it possible that it's in backward?

We'll boys it looks like my flex plate is on backwards, I thought the motor was never messed with but I was wrong

Thanks Shifty!

My 383 is still on the stand, and when I looked at it I could see how that would really 'shift' things!

I'm sure his TC was pulled out as well.
