LA Windage Trays
What year (s) does the truck 360 have a windage tray?
factory roller motors had one 360, not 318*
police motors have them (both 318 & 360)
360 EH1 code motors have them so that's a bunch of 76~ 360 4bbls motors
360 E58 motors-- cop motors, but not always found in cop cars
or sedans
318 E48 318 cop motor (*318
police rollers got one)
A38 (i think) fender tag would indicate "severe duty" or "fleet" so that *might* get one.
a lot of truck 360's got them, but they'd be 4bbl units. so pretty much any year is a possibility. without a fender tag, and because these things are all 50+ and anything can happen it's kind of a crap shoot as to what you might get.
the best way to verify is just to drop the pan real quick. the engine production numbers (on in the front of the block under the head) will tell you, but other than that there is not a quick external visual that will indicate a HP/SD motor with a windage tray.
so basically anything from 73~90(ish) with a 4bbl could have one.
