I have two engines that I would like to know which camshafts they have. Are there casting numbers on the cams that I can interchange? The first engine is a 302 out of a 84 Mustang and I would like to double check if it has the HO cam. The other is a 351w from a 82 F150 and I am wondering if it has the 2v or 4v cam.

 

No casting numbers that will decode to anything usefull I don't think. Get a dial indicator and measure lobe lift or valve lift with the cam in the motor, that alone will tell you what cams you have.. assuming they are stock.

 

Some of the later roller versions had letters stamped near the distributor drive (ZL and ZE), not sure about the earlier version though.

 

There are no casting numbers on camshafts, and casting numbers cannot be cross referenced to part numbers.

Some cams have markings on them.

D5OZ-6250-A .. Camshaft ~ 1981/84 Mustang 255/302 exc. H.O. / Marked: DG or DH with reverse D

D3OZ-6250-A .. Camshaft ~ 1982/84 Mustang H.O. / Not marked / This same cam was used on 1973/75 351W's installed in passenger cars.

D6OZ-6250-C .. Camshaft ~ 1981/85 F150/350 351W 2V / Not marked.

No 351W 4V's till 1984.

 

Thanks for the help. I pulled the cam from the 302 and it has a HD (DH depending which way I look at it) so from the info it has the ****ty cam. There is also #27 on it.
The 351 isn't the original engine in the truck. It has a rebuild date on it and was bored .040 over. It also doesn't have the original intake.
