[Tigers] weakness

[James Armstrong]

Hello


The cam drive gear on my engine (and yours) had nylon teeth that lost four teeth as I pulled quickly out of a stop-light. Timing chain skipped. On later Small Blocks, Fords dispensed with the nylon teeth (noise abatement) as they failed over time. Since the engine was way out of time, the result was a piston that came in contact with a valve, broke the valve,which rotated and split the piston, etc. I was fortunate in that I was able to save the block, crank, and both heads.
Bottom line: if you haven't done so, change that verdamt cam gear and chain while you're at it.
