good to see you making progress. i had the above cam made by mike jones for a 406ci sb with 9.8 compression, he spec'd out more lift but was reduced for valve spring longevity.

your cam seems a bit mild, especially for the compression. a cam will make or break the deal, if what you have doesn't seem right, go with something else.

with a custom cam made by "someone good" you get ramp rates that let you turn the motor higher rpm from what i understand. i've heard over and over again, it's how the lobes are ground that makes a difference.

also the above was for efi, your carb may require different stuff.

good luck

Almost the same cam. The difference in net lift is due to your specs. using 1.7 instead 1.6 rocker ratio. If I wanted to go to 1.7 rockers they would be almost identical.
Thanks, Don
