What compression ratio do you have? If you don't know the compression ratio, what type of pistons do you have or part#? Has the block been bored and decked? Do you want to run a hydraulic or solid lifter cam? What kind of car or truck is the engine to be used in?

I hope it comes out this time? And I hope it helps you out!! If you click on it it will enlarge and then you can magnify it> This info is basic to all cams. the phone number is no good as PAW is down sized to only Chrysler parts Mainly Hemi's.

Your big block sounds like a very mild build so a range 2 duration is what i would recommend in whatever brand of cam you like as long as you stay in the range of duration suitable to your build you'll be fine.

pay particular attention to spring pressures and installed height ( your heads are already done) so match them to the cam you order or you may have to redo them! Your cam lift may make it necessary to change push rods! your differential ratio and torque converter may need upgrading. If you go to a (range 2 or 3) bigger duration cam. So on the chart I posted pay attention to the particulars, like heads, compression, gear ratio, convertor, etc.

A custom grind is a little overkill on a basically stock engine! As many grinds and manufacturers that are available its just foolish to waste the money on a custom grind!!!!!

choosing the best cam for a BBC

Check with Summit Racing to see if you can use your valve springs with this cam. Summit Racing SUM-K03052 - Summit Racing Street & Strip® Cam Kits - Overview - SummitRacing.com. I would buy the spring kit and use this camshaft. Summit Racing SUM-K1301 - Summit Racing® Cam and Lifter Kits - Overview - SummitRacing.com
