You're actually speaking of http://www.ipdusa.com/ There are many versions of the PRV-6 so you need to look under the specific number like b28 or b280. I don't know which is the right one for the D or if they make one that would fit the D. If you look at my spec page at http://members.home.net/shirazcupala/delorean/specifications.htm you'll find a link at the bottom to the guy who did my engine swap. He races a later model PRV from an Eagle Premier (like mine) but with different cam shafts (I think from IPD since that's one of his sponsors). Note, that engine is even firing, so many other things are different. shiraz DeLorean #2860 Seattle, WA --- In dmcnews@xxxx, petleech@xxxx wrote: > Speaking of performance, there has got to be some European outfit who has > developed performance cams or headers.
