The factory roller engines refer to roller lifters, not roller rockers. I'm thinking that the trucks never had factory roller lifters.

93 5.0 has the roller cam and lifters. it is a ho motor 87-92 has the casting in the block, but does not have the roller cam. I think 93 was the only year, but have never been inside newer ones. if you go to jasper, or mid atlantic for a rebuilt motor, they actually say 93 only. I have a 93 ho, and it runs stronger than my 90 5.8

My last post should have read "roller rockers" in the last sentence. My mistake...

The trucks did have roller lifters beginning somewhere around 93.
