Timmyb Posted January 2, 2016 Share Posted January 2, 2016 My truck has is an '84 build, with a 2v engine. Tag on the engine says "date of service assy mfg" and is marked at 6/89. Is that it's build date? Quote Link to comment Share on other sites More sharing options...
j hancock Posted January 2, 2016 Share Posted January 2, 2016 Looks like a replacement engine was put into your truck.I believe 1988 is the last year of production for the 2 valve to be put in trucks on the assembly line. Brand new 2V engines or ReMack 2V engines would have been available through the parts system for several more years and the actual build date of the engine would be stamped on the tag. 1 Quote JimIt doesn't cost anything to pay attention.

j hancock Posted January 2, 2016 Share Posted January 2, 2016 I was thinking EM6. 1 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
blackdog2 Posted January 2, 2016 Share Posted January 2, 2016 Ive done a couple DMM 1989 + with E-6 2 valve heads so they can put the tip turbine on and no inter cooler in front of radiator but they had the larger connecting rods. 1 Quote Ed Link to comment Share on other sites More sharing options...

Timmyb Posted January 2, 2016 Author Share Posted January 2, 2016 Thanks guys. Are remack engines tagged differently? IE, would it actually say remack? I've seen a remack diff before and the tag screamed at me "remack"!I guess I assumed mack would of phased out the 2v when the 4v came along.

kscarbel2 Posted January 4, 2016 Share Posted January 4, 2016 Thru at least 1988, the 2VH Maxidyne EM6-275L (1,800 rpm) and non-Maxidyne 2VH E6-350 (1,950 rpm) were respectively the standard and optional engines in the DMM-600. 1 Quote Link to comment Share on other sites More sharing options...
