I just bought a RAM clutch kit from Mustangs Unlimited for my 65HIPO. Its part number 8850501 and advertized as a 10 1/2 inch clutch. I look at the box and it says its 10.4- what gives? Is the 10.4 correct or just something this company feels is usable as a replacement?
If this part is wrong, does anyone know of another major retailer who sells the correct size kit? Thanks for your help.
The original Hipo clutch disc is a C3OZ 7550 F and is 10 1/2 inches. The Ford replacement Hipo disc is a C7ZZ 7550 B and although it is listed in the Ford parts book as a 10 1/2 inch disc, it is actually closer to 10.4 inches. I have both of these discs in my stock and I have personally measured them so this is not a guess on my part.

Could I jump in with a clutch question: I am finally getting ready to build my '65 "K" convertible, and I have a partially worn out left knee acording to my Doctor-he says to come and see him when I'm around 60-62 for a replacement-I want to drive my "K" with the 4 speed all I can once its done so I'm looking for a clutch setup that will certainly still grab but is the lightest I can get away with in peddle pressure, can anyone make recomendations?? the only other way I can go is with a C4 and I don't want to do that!! Thanks!!
The clutch was referred to as 10-1/2", 10.4", or 10-3/8", depending on the source. They are all the same, as the smaller non-HiPo will be a 10".
There are three clutches for the small block: the standard 10", the heavy-duty which was 10½", and the 289 HiPo which was 10½". The HiPo has the strongest gripping power and my foot could definitely tell the difference. I also have used the heavy-duty 10½". It was definitely easier to depress than the 289 HiPo. But for pure pleasure in driving with light foot work, the standard 10" is a good choice. I installed one of these in my 1963 Fairlane and loved it. It was still plenty strong to spin the wheel in 1st gear, but much easier to depress.
It is somewhat difficult to find Ford remanufactured pressure plates and discs, but they are my only choice for clutches. They wear well and don't chatter.
It is also important to remember to make sure that you have the heavy return spring for the clutch pedal on the brake pedal hanger bracket as it acts as a pressure relief once the pedal gets about 2/3 of the way to the floor. If you do not have the spring it makes the clutch pedal get even harder to push down as it approaches the floor.
