Funny Noise
When I turn off the ignition, as the motor comes to a complete stop from idle, I can hear a strange very brief whoosh of something like compressed air. Kinda like a loud wheeze, it's hard to put into words.
The 1980 long-block motor received a stock rebuild about ten years ago and only has a 2,000 - 3,000 miles on it. It was in storage more than 3 years until recently when re-installed after the rotisserie restoration. The original 273 Commando AFB was re-built ten years ago as well (I just slapped it back on this time without having doing any new work on it). I just drove it on the highway for the first time in 3 years (a ten-mile jaunt). It seems to idle a little rougher than I remember it, but I don't notice anything else amiss (I did replace the spark plugs before the drive). The distributor is a automotive chain store single point style replacement.
First photo shows engine installed after the rebuild ten years ago. Second photo shows same engine installed after being repainted to correct Commando color scheme. Third photo vehicle as purchased, last photo currently awaiting headliner and windows.
