Re: Modified Drive and Clutch gears
You're right about the early small block Chevy. Also Olds and Pontiac had some issues with undersized main and rod bearings. Cold, the engine would start just fine but when it got up to temperature the bearing clearances would tighten up and the darn things wouldn't turn over.
The Ajax/Comet trick worked on those too...but we NEVER told the customers what we did.
