sbc starter issues yet again

recently i replaced the flexplate and starter in my camaro but its still grinds now and then.usually only when hot out or if the battery is a lil low

ive tried with shims, without shims and its always the same.

somone told me to cut a shim in half and only shim the outer bolt have any of u guys head of this before ?

btw this is an offset bolt pattern starter 168T flexplate
the engine is 9.2-1 cr so not high by any means

Could the nose of the starter made to fit a 153 teeth flexplate? Not a 168.

not sure what u mean

edit

my understanding to use a 153T flexplate and starter i would have to drill and tap the inner inline bolt hole on the block

A page that has some info on shimming a starter is here.

Actually the instructions in my rebuit starter for a 69 Camaro 327 says to shim only one end if needed. I usually use a large paper clip to space the gears, but the starter came with a piece of wire that was about twice as large for the spacer. Close is not good.
On a chrome mini starter I have used, I had to use double spacers (4) to drop it low enough to get good clearance. I decided not to space one end since it would throw the angle slightly off on the mating surfaces. I was concerned about that but the instructions from the rebuilder did say to use that method.

Is your starter supposed to have a support bracket on the end that bolts to the block?

I had about five cars with start problems,,, Not sure what going on with these new starters today..They are machined wrong..... I started using this starter on all my cars,, Never had anymore problems... This is a great little starter,,, I even use it on all my big block chevys as well...

just wanted to say thanks guys , a single shim on the outboard bolt cured my starter issues.

i even shut the car off and left the fuel pumps/radiator fans running to kill the battery and still had no issues with the starter grinding

for what's it worth, my former neighbor had a chevy 350 that was ALWAYS giving him fits with the starter grinding.

he found a speed shop that told him that some chevy blocks (certain casting numbers I guess) were actually machined wrong from the factory, and the mounting pad for the starter was 'too tall' so no amount of shimming would ever fix the problem.

he bought a new starter, had a few thou milled off of the mounting surface, and never had starter issues again....

he wasn't a diy hot rodder so he couldn't give me any more detail then that.. just something worth looking into

Second the milling fix. DId it many times I always attributed it too cheap repop starter nose castings though. I always tried to avoid the whole problem by taking the dead original starter to a local rebuilder.

Red: i just rebuild them myself :> my engine isn't particularly hard on starters so I don't wear them out too often.. but the heat from the headers causes issues with the solenoids sometimes.

i've thought about going to a mini starter just for more room around the headers *shrug*
