Another "Different Cam?" Question about my 418 build.

[vector1]

hello don

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

mark
