m20 bolt markings
« on: September 27, 2013, 06:58:01 AM »

Hi there,

I have a m20 with the following numbers on the casings- 5660, 7584, 4685.

Ive searched around CRG and Team Camaro but am still after a little more clarification on the bolt markings required for the given sections of my m20.

My camaro was assymbled at the Norwood plant 68...

Thank you.

I have a 68 Muncie M20 and the cover bolts all have a letter L on the head seems to be common, the taillhousing bolts seems to be marked SBC

may look at this thread I was trying to determine what was original for my car

69 RS/Z DZ302 Daytona bumble bee
69 T/A clone LS6/6sp
69 Nova SS 396

Going to put the name and number out there who did my M21 last summer. Restores, rebuilds and date codes. Wonderful work. Guarantees for life " unless you throw slicks on and screw it up at Norwalk ,than your #$$#ed" (quote)---he also restored and set up the Hurst.  N/E Ohio   440-409-9620    Steve

Was referred by the man who builds our automatics.
