you may be able to quote the part number to the original manufacturer.
or if there is a cam grinding place near where you live they may be able to use a profile tester (digitiser) (if they have one).
or the only way that i know of is to install and degree although this may still be hit & miss unless you the advance that it was ground for.

are they made by ford? look on the end of the camshaft. if one of them says "C7FE", run it! that's the ford "lemans" cam. its an oldie but a goodie.

I beleive the 306hp cam was the standard Ford HP289 solid lifter item. Shelby put a 715vac holley on a std 271hp 289hipo, and called it 306hp. A good factory cam in it's day, but way out of date now. Lots of seat duration(to make it sound bad), not a whole lot at .050(1963!), wide lobe separation and very low lift(streetability and 100K durability). Several big cam companies make 'blueprint' copies of this cam, and specs are available on thier websites or catalogs. If it is new and unused, probably worth more to a collector than to a racer, imo.

If you have a digital caliper or a micrometer measure the lobe lift and multiply it times your rocker ratio and that will tell you valve lift,If you dont have the tools a local machine shop should be able to measure it for you just a thought.....Towman
