Camshaft ID help?
Need help identifying a camshaft on a engine that I purchased. The part number on the back is poorly stamped and I can only make out a few digits. I can see three numbers clearly and one letter, 785-W. It looks like there are two more digits in front of the 7, but I can't really make them out. Any help would be appreciated. Thanks.....Terre

Maybe it's just me, but as cams/lifters seem to be pretty reasonably priced I probably wouldn't buy a used one from Indiana-Ohio-unknown history-etc..

It's not just you, but there is a nice market for used engine parts including cams, and lifter sets. Just take a look at Ebay's completed sales for SBC cams, they sell on average one a day, so 365 a year. Now take into consideration Craigslist, swap meets and sites like this, just imagine the number that are sold. Although you may never buy a used one, many can not afford a new one. Sure the cost of a cam and lifter set is reasonable, on it's own, but when you add in all the other parts, and labor to build an engine it can become quite expensive. I edited my original post so hopefully we can stay on track and identify this cam. If not it's no big deal to me, I just hate to throw a like new cam, that someone could use, in the scrap. Thanks for your input.

Most cams are not marked well. One way to tell what you have is with a degree wheel and a dial gauge....set it on the lobe and plot what you get while turning the lobe through 360 degrees. Do this on both intake and exhaust lobes to get results from both.
You'll at least get lobe lift and duration at minimum.
