A guy in the Chevelle Club has this and we are descending on his home/shop today as a club tech/work/learning session and should be interesting. About half of the members, including the owner, weren't born yet when this engine was made.
Then there's us "seasoned veterans" that still have point files, feeler gauges and dwell meters...
