Lunati Retrofit Hydraulic Roller
Very nice street set up.
It appears that the Magnum roller blocks do not have the same lifter issues as the LA block.
I have seen other forum members come to the same conclusion.
I do agree with you, however.
Mine's one of the oddball "transition" years.
Mine is actually classified as an LA block. (mine is from 1991 Ramcharger)
360's from about 1989 to 1992 were classified as LA blocks but had roller lifters from factory and the "308" heads.
The 318's started having them in the late 80's as well, if they had the "302" heads it was almost guaranteed. From about 1988 to 1991.
They are reports of them starting as early as 85 in M-bodies, I can't verify this for sure, but I thought I read about it sometime in the past. (if I can find that book again)
I also had quite a few people tell me that the 308/302 heads are really good. (just gotta block the smog ports) and port them to their potential. As I was going to replace them with ported 340 big valve J-heads. The guy at Hughes Engines was the one who told me that on the phone, or buy one of their worked over E-quest magnum heads.
These were "transitions" into magnums, it's also funny how the 318 is first to get the roller treatment and the magnum treatment (1992 vs. 1993 for the 360)
I have also heard some people call them "Pre-mags".
Now only If I can find that book again, I loved that book although a bit dated info-wise, still a good read.
It's funny, I still have factory service manuals For 1984 and 1988 D/W series trucks.
