The only thing I can suggest is to do a Yahoo search on those numbers with key word camshaft.

With the block on an engine stand, install the crank and one rod/piston in the #1 hole. Install the camshaft with the timing set you intend to use. Install a degree wheel on the crank and bolt a wire pointer to the front of the block. Purchase a cam checker of this type....

...and degree the cam per instructions....

Once you have established the 0.050" tappet lift specs, match the static compression ratio to the cam. This is just bass-ackwards of the way this should be done. Normally, you would establish the static compression ratio you want to run and then match a camshaft to the SCR to achieve the desired results. The tools to degree the cam will cost more than a new camshaft on which you know the timing to begin with.

This is the Camshaft Machine replacement cam for the GM part number 3863151 small block Chevrolet hydraulic lifter camshaft (350 HP 327 cu.in.). This is a single pattern camshaft having 222 degrees duration at .050" cam lift. Lobe lift is .298", for a gross valve lift of .447" with the standard 1.5:1 ratio rocker arms. Lobe separation is 114 degrees. Cam timing at .050" is: intake opens 1 degree BTDC, intake closes 41 degrees ABDC, exhaust opens 50 degrees BBDC, exhaust closes 8 degrees BTDC.
