Martin G: check me out on this one (or Darren B)... Was in junk yard today getting dash clock for one of the Lincolns. Close to donor car was a late model (1990) Volvo 760, so out of curiosity I popped the hood. I thought PRV had fallen out of favor by then, but this was like looking in a mirror. Not only PRV, but had idle speed motor, microswitch, etc (horrors) and some sort of Lamda type device (double horrors). Studied block very closely but could see no external differences, other than bolt on accessories of course. If original to car, PRV must have been in production at least through 1990. BTW junkyard owner wants $200 for everything from transmission forward. Late model 760's are very plentiful. In roadable condition only fetch upper $hundreds to low $thousands (eBay). I'm sure flywheel is different, but couldn't remainder of block simply be dropped into DeLo with demo'd factory unit (overheat, death by storage, etc)? Was under impression you had to find early 80's 760, which are rarer. BTW: this is all academic. One more vacuum leak and my R30 should be perfect (as perfect as a PRV can be...) Bill Robertson #5939
