LA318 question

He ment to copy and pasteā€¦.
:rofl:

  • 1985 - Federal 318s went to a roller cam and lifters (unless they had the four-barrel carburetor), reducing friction and increasing longevity; valve shrouding was used to increase the burn rate; and the compression ratio was hiked from 8.4:1 to 9.0:1. Truck engines did not get the roller tappets at this time, according to Chrysler's literature of the day.
  • 1986 - 318 receives high swirl heads
  • 1987 - 3.9 is developed from 360
  • 1988 - 318 get hydraulic roller cam; 3.9 and 318 get throttle-body fuel injection
  • 1989 - 360 gets hydraulic roller cam
My 88 teener has a 2 bbl carb from the factory not TB injection. This is one reason I'm asking the question about the valve train. Even the factory parts books list both the roller lifters, and/or flat hydraulic lifters as being in the 318. The dealer can't tell me which it has, even with the vin number. Just curious about this. I'm not going inside to look. Engine has no oil leaks, and I'm not going to open a can of worms, just to satisfy my curiosity. I was just wondering if I could tell, without going inside. I wouldn't mind using a bore camera to take a look inside a valve cover, or somewhere else.
Just another thing. I had a 85 5th ave with a 318, and it did not have roller lifters. I was inside that motor.
