  • 2001 ST200 cams

    I am fitting the above with the same vehicle heads to a 99 non SVT engine. The cams are from one of the last ST200's in the UK. Done a search for the part numbers and have found that the cams I have are the 8mm pitch (1s7e DA)instead of the 3/8" pitch (f73e BA. Can these be fitted with the same timing gear?

    Thanks in advance

    No, you must use the cranksprocket, chains, tensioners, and guides for 8mm pitch systems. You might ask around to see if anyone on the boards has 8mm parts left over from their 3.0L conversions.

      Are you sure they are from an ST200? and not an ST220? My understanding from a Ford Duratec engine engineer was that all SVT and ST200 cams were identical and the ST220 went to the 1s7e gears. If they are the ST220 cams, you definately want them anyway as they are even better than the SVT/ST200. You shouldn't have any difficulty locating the later timing setups from someone here in the states that has swapped SVT cams into a 3.0L

        1s7e-da = Svt/st200
        2s7e-ba = St220

              As far as torque values and overall top end power. Are the st220 cams better then the stock 3L cams
              Luck is where opportunity meets preparation.

                had all 3 sets of cams in front of me this winter, st24, st200, and st200, as I had bought a 3l st220 engine to drop into my st24, and bought a st200 engine to get the cams for my port matched 3l
                did some measuring and no surprise to see st200 cams have more duration on inlets and exhaust than st24, and st220 cams
                comparing st24 to st220 cams show the st24 inlet has more duration on the short runner port than the st220 inlet , but the 220 exhaust has a bit more duration than the st24
                anyway st24 cams have green band, st200 orange band, and st220 black band
                I have a set of the finer pitch chains, tensioners, guides etc, which I was going to throw into the st24 engine along with the st220 cams
                could do you a swop for the st24 cams , chains tensioners, etc, you would just have to stand the postage costs
                as regards the v6 I just rebuilt my st220 engine this winter
                crank, rods, pistons, flywheel assembly etc, dynamically balanced, main and big end bearings supplied by chesman engineering in coventry
                f1 rods and cp pistons from Campbell enterprises in usa
                gaskets, stretch bolts, etc from mounttune in uk
                ported the heads, manifolds myself, and had the valve seats recut 3 angles
