Hopefull I'm not jumping here too late.
Sorry guys but Ford in fact DID use 351W's up until '91 in the Crown Vic Police Interceptors P71's, last of the old boxy body, and in the wagons. Not sure if the wagons motors were different then Police other then extra coolers ect.
I almost bought one, a P71, a few years ago but it was to ratty. There is one on ebay now, item # 2437937321.
I too have a police 351 but from an '89 I believe, got it as part of a trade, and I'm also looking for more specific info about them as I plan to go with at least the 393 stroker. What I know for sure is 351's in '79 the main webs were cast a little thinner(maybe other areas too). '72 the deack height went up from 9.48 to 9.503, and somewhere around '82-'83 the rear main seal changed to a one piece style Not sure if they changed anything for the police/truck blocks. All 351 Police/Wagons had the V V 2bbl. Trucks had either 4bbl carb or fuel injection. After 94 they got roller cams. I have no idea if the lifter bore height was changed from the '80's - '91 Police engines but I do know they had to be machined for the rollers. All 351's used the 28 oz imballance. '98 was the last year of production.
Now to just figure out if the police blocks were anything special. :-/
Bumpster, not that I know what it means, but does your block have "WCP-9" cast in the lifter valley? My heads (not that it matters, I'm going aluminum) also have "WCP" on them. They are E5AE's. Probably crap anyhow. ?
