Ok. I've been reading/following since the thread started & went back through recently looking to see what engine changes were made along the way. I knew the heads were different & the carb updated but I didn't recall the cam change. Sounds nice. Not too much but you definitely know its there. Curious on the specs w/that quality of vacuum so I'll keep reviewing the thread.

Comp Custom cam specs are as follows:
3014 lobe on a 110 intake center line
3015 lobe on a 118 exhaust center line

4 degrees advancement in the cam and timing chain in the “straight up” position.

Lobe specs are below – lift with 1.5 rocker.
Lobe - Dur - @.050 - .200 - lift -- 106 -- 110 -- 1.5 Rocker
3014 – 268 – 218 – 143 -- .356 -- .058 -- .047 -- .534
3015 -- 274 – 224 – 149 -- .358 -- .068 -- .055 -- .537
