I'm trying to find some info on a cam that I've got. It's for a small block Chevy. Is brand new, and has these numbers on it. 115213 and 241608. No other markings. Any help would be greatly appreciated.
you can measure lift, duration, etc by using a degree wheel and a dial indicator-- using what we used to call a cam jig. you can then confirm cam spec, confirm duration at .050 when applicable, etc. this is always the best way to confirm real deal versus advertised. -scott noteboom
The cam is already in the engine. I thought someone could maybe tell me what kind of cam it is by using the numbers. Are these numbers useless? I'd be happy to know what kind of cam I've got before installing the engine. I'm building a drag engine not a dump truck. Thanks, Dools
Maybe you could take a valve cover off and set up a dial indicator on top of a valve and crank over the engine by hand and measure the actual lift at the valve. Do it for intake and exhaust in case it's a dual profile cam. Take out the spark plugs and it won't be that hard to turn the engine over using a breaker bar. If you have a degree wheel of some sort, you can probably figure out the duration too. The lift alone should give you a ballpark idea of what sort of cam it is if you compare it to some charts of cams from Crane or Edelbrock or Comp Cams.
Check the on-line catalogs from all the major cam companies, and maybe you'll find that part number in their catalog. Check Crane, Comp Cams, Erson, Edelbrock, Isky, etc. Maybe go to Summit or PAW and do a search with those part numbers and see if anything comes up. Probably one number is a part number and the other number is a batch or date code. Good luck It could also just be a stock cam, so maybe check a Chevy part numbers book.
you can still do this quite easy with the cam in the motor. pull the front cover so that you can degree wheel the cam, and then measure movement through the valve cover. -scott noteboom
