Thanks, George!

I am sure you will - I look forward to a trip to the West Coast someday.

I wanted to post up my Cam Specs and Flow Data - I will post the theoretical (Dyno2000) HP & Torque.

The Cam came from one of George's recommendation (Sticky #3). I think the sticky that I pulled this recommendation from was modified (I can't find it anymore).

Custom Ground Hydraulic Roller Tappet Camshaft

Camshaft Spec:
Grinder: Bullet Racing Cams of Olive Branch, Mississippi
Telephone (662) 893-5670
Engine: Ford 351 Cleveland, 4V cylinder heads
Hydraulic roller tappet camshaft
----------------------------------
Intake Lobe: #HR275/3533 (CRA)
Intake lobe mathematic centerline = 112° ATDC
Exhaust Lobe: # HR287/353 (CRA)
Exhaust lobe mathematic centerline = 116° BTDC
114° lobe separation angle (camshaft degrees)
---------------------------------
Exhaust valve opening = 79.5° BBDC
Intake valve opening = 25.5° BTDC
53° overlap
Exhaust valve closing = 27.5° ATDC
Intake valve closing = 69.5° ABDC
---------------------------------
275° advertised intake lobe duration
220° intake lobe duration at 0.050"
Intake lobe hydraulic intensity = 55
0.611" theoretical intake valve lift (1.73 rocker ratio)
---------------------------------
287° advertised exhaust lobe duration
230° exhaust lobe duration at 0.050"
Exhaust lobe hydraulic intensity = 57
0.610" theoretical exhaust valve lift (1.73 rocker ratio)
---------------------------------

Here's my Flow Data - measured. My heads were ported by a 351C Master Builder.
