Ok....I follow what you're saying, thanks for the feedback! So even with Howell knowing these specs, you still had to work with them to burn a couple extra chips to get it right?

Here are the cam specs the engine builder sent me for the 360 being built:

Adv. Dur. - 262 int/270 ex
Dur @ .050 - 218 int/224 ex
LCA - 112
.493" int/.500"ex

The CR will be 9 to 1, and it will be running an Edelbrock Performer intake. I've yet to decide on what dizzy I'm going to run, but am currently leaning toward the DUI
