old melling cam specs

Post by dondon »

years back (late 60's) a friend had a 289 in a 65 ford falcon and he did the normal hop up, intake, 600 holley, hooker headers, and a melling hydro cam. I searched for all the specs but can't find anything. The cam was pn ryb12. I was wondering if anybody here knew the specs for this cam (.050 duration, lift, lsa, etc). Thanks, don

Most generic cams such as this one mentioned use the SAE method of determining lift duration and LSA.
It will seem much larger using those numbers then the current @50 method of measuring or checking cams.
Like the difference between the advertised and @50 duration listed for cams today.

If you have the cam just degree it using the @50 method.
If not call melling or others directly talk to their tech.

memory being 50 years removed I would of guessed the way I remember the rough idle that it was more 218 @ .050, but the 288 advertised duration and the .461 lift sound right. thanks for all the answers.

A Comp Xe262H-10 will probabily work a lot better.

Are you sure your looking for RYB 12 cam info and not the SYB 12 cam?

The SYB 12 cam, is a clone of the 271 hp, HP 289 or K code engine. Ford used that 228 @ .050 cam lobe on the FE engine, also.

There are better cams, that one is kinda "lasy" but durable. I'd go with something in the 230/236 @ .050 and at least .500 lift.

no it was the ryb cam, I seen the number on the back of the cam, he still has it. It has been stored for 40 years and he is going to use it again as he trying to relive his childhood in another 65 falcon. it is in good shape.

The older the cam, the faster it wuz; nostalgia isn't about numbers. He will be slow, but the memory is worth it.

jack vines, who fifty years ago knew all those SBF cam specs from memory. Biggest disappointment was the C90Z-6250C Muscle Parts Performance hydraulic cam. Wasn't until years later I learned Don Sullivan took the 289 HiPo profile and removed the clearance ramp so it would work with hydraulic lifters, intending it to be the 4-barrel 351W camshaft. Supposedly, it wouldn't pass emission testing and automatic trans idle in gear quality, so it was sold off as a Muscle Part.

In my Melling catalog (same one as pictured above), Melling only lists 2 cams that start with a "R", ROC9 & ROC10, both for the late BB Olds engine.

Maybe the part # you saw was partially stamped and looked like a r?

From '67 to 74, I had 3 "K" code engines, in two different cars ('64 Fairlane SC & '65 1/2 FB Must) They both ran good, for that time and would rev to 7k. But, there are better cams now.

That old Melling cam # is shown in the Clevite catalog Cross Reference. It is common to the brand/part#'s I posted including the new Melling part #.
It is what it is. You can measure the cam lobe lift with dial calipers to verify.
