      the max you can run is dependent on the size of the valves and piston style, and your valve springs

        "It Depends". the almost-always correct answer in case of vague questions.

          Also, I'd upgrade the heads before the cam on a 351W crown vic. The cam isn't THAT bad. it has around the same lift as an HO cam, and more duration.

            Saw edelbrock 2182 kit for sale cheap. I wanted to compare specs with stock cam. Stock 351w bottom end and iron heads would be the application. I dont know how to be less "vague".

              Exhaust Lift (mm) : 6.604 mm
              Intake Duration : 195 Deg.
              Intake Lift (Inches) : .260"
              Intake Lift (mm) : 6.604 mm
              Lobe Centerline (Exhaust) : 112 Deg.
              Lobe Centerline (Intake) : 103 Deg.
              Lope Separation : 108 Deg.
              Overlap : 55 Deg.

              CS764
              Cam Type : Hydraulic
              Exhaust Duration : 221 Deg.
              Exhaust Lift (Inches) : .283"
              Exhaust Lift (mm) : 7.188 mm
              Intake Duration : 206 Deg.
              Intake Lift (Inches) : .278"
              Intake Lift (mm) : 7.061 mm
              Lobe Centerline (Exhaust) : 114 Deg.
              Lobe Centerline (Intake) : 116 Deg.
              Lope Separation : 115 Deg.
              Overlap : 46 Deg.

              these are the two cams listed for Crown Victoria 351W applications. Just by sound and feel I'm inclined to believe my 85 came with the 764 but it's unclear when the switchover date was or if there even was one. Like I said, on paper, not that bad. I'd go for new heads a long time before I switched it out for a cheapie one-size-fits-all camshaft.

                The CV/GM Cop Cars got the 351W HO with the hotter cam from 1980 on according to my Ford Master Parts Catalog. The Sealed Power CS764 appears to be close to the Melling SYB-35 which is the replacement for the factory 351W HO cam. From a previous thread NAPA lists the CS764 for the CV Police 5.8.

                    What are you planning to do with an old factory HFT camshaft? I don't have Ed's expertise, but my suggestion is always to use a HR cam whenever possible.

                      Motors on its last legs. It was for sale for $30 still in box. I figured have some fun and then swap.

                          Unless you have a F4TE block, a HR camshaft in a 5.8 is not a cheap option.

                            How does one run a flat tappet cam nowadays w/o much zinc in the oil?
