Question finding cam specs

I recently acquired a new cam for a sbc. I know little or nothing about it other than it is a high performance cam as the paperwork and cam card were lost. If I can mic the lobes and find out the specs would that help or wouldn't that tell me anything?

Mike across the highest and lowest point on one of the lobes. Next mike across the lobe 90 degrees from the previous point. Subtract the smaller number from the larger to get the lift at the cam. For total valve lift, multiply the cam lift by the rocker arm ratio (usually 1.5 for Chevy small block) to get the total lift at the valve. Do this for both the intake and the exhaust. This will not give you the duration though. If you know the cam manufacturer you can check the cam # found on the end of the cam to get the specs.

Hey dude,

You can get the tool to do the job from summit racing equipment. it's got a dial indicator on it and it mount to the block with the cylinder head off, you can measure lift and duration with it so don't worry, if all else failed and simple dial indicator,and a cam degree wheel would do the job.

mystery solved-This is a factory 300HP cam that came in some 327s. I had a 64 impala ss with one. Not a race came, but it was high performance. I don't think I'll use it in my street rod, but I have a GMC pick up I use to tow my RV with. I plan to add headaers this summer and might throw this cam in at the same time. Any opinions?

If it moves and shouldn't....Duct Tape.
If it doesn't move and should....WD40.

That's all you need to know.
