the max you can run is dependent on the size of the valves and piston style, and your valve springshttp://secondhandracing.com/Home.aspx

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.
85 4 door 351 Civi Crown Victoria - Summer daily driver, sleeper in the making, and wildly inappropriate autocross machine
160KMs 600cfm holley, shorty headers, 2.5" catted exhaust, 255/295 tires, cop shocks, cop swaybars, underdrive pulley, 2.73L gears.
waiting for install: 3.27's, Poly bushings, boxed rear arms, 2500 stall converter, ported e7's, etc

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".Town Coupe [X]

CS764
Cam Type : Hydraulic
Exhaust Duration : 221 Deg.
Exhaust Lift (Inches) : .283"
Exhaust Lift (mm) : 7.188 mm

Lobe Centerline (Exhaust) : 114 Deg.
Lobe Centerline (Intake) : 116 Deg.
Lope Separation : 115 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.Last edited by johnunit; 03-22-2011, 11:59 AM.
