1980 cj5 chevy 350 tbi swap issues

Having issues with the tranny and clutch plate and flywheel to the back of the motor with the bell housing. I got it all together and couldn't get it to turn over, so I had some buddies come look at it and found there was metal shavings in the bottom of the bell housing. I haven't taken it apart yet but I bought the parts from a guy who does the swap for a living, so idk why I would have the wrong parts I used a 93 camaro starter and it was a 153 tooth flywheel. And it all bolted up I did however have too really tighten the bolts to the motor and bell housing. Anyone know what my issue may be

Did the input shaft go into the pilot bearing all the way? I've read on here that if the bearing is in too far it becomes pinched and distorted,then the input shaft doesn't fit correctly.

Is the starter for the 153 tooth flywheel?

Can you turn the flywheel by prying on the teeth with a screwdriver? Basically making sure it's not a "rotating" issue... but a starter/starter gear issue?

As far as I know it all went in like I said though we had to really tighten the belhousing down to the engine block and we put some ummmffff on it to close the gap.i haven't tried the flywheel with a screwdriver all I saw was the shavings in the belhousing

My buddy thinks the flywheel is grinding on the top of the belhousing and that's why it won't turn over said to drop the tranny again and take a look inside.


I am just concerned what parts would be wrong if it all bolted up and I supposedly got the 153 tooth flywheel

You should not have needed to work hard to bolt them together. Something is wrong there.....

So does that make the pilot bushing the isue? And if so why would there be shavings from the belhousing at the bottom of the belhousing?

Possible, you'll have to backtrack your steps. See if you can move flywheel. If not; start loosening bolts to find problem,then correct it.

'93 Chevy tbi 350 from a pickup, 1987 700R4 trans from a blazer, front d30 from a early '70 cj,rear d44 from the same cj. I put a Chevy fuelpump in my tank and added the Chevy wiring harness to my cj harness to make it run. Works great so far......knock on wood! Lol

Conversion wasn't bad. With a family of 5 and only 1 income,money took the longest get.

Were the shavings aluminum or steel? If they're aluminum (check with a magnet if unsure), then it sounds like the flexplate is probably contacting the inside of the bellhousing.. with the teeth shaving off aluminum. If the shavings are steel, then it's probably something else.


Also.. did you physically count the teeth on the flywheel to verify 153.. and not 168 teeth?

You didn't happen to use some aftermarket bolts for the flywheel, did you?

I ask because I found that some bolt kit's, that are advertised to work for AMC engines, will actually be too long, and the bolts will rub against the back of the block.

I don't know if the above info applies to a 350, however.
