5,500 Max RPM
9.1:1 Comp
Earson Cam
   Lobe Seperation Angle 112
   Valve Lift .519
   Duration Int/Exh - 296/306
   Duration @.050 228/235
   16-17 inch idle at 900 rpm
2.11/1.77 Valves Ported Heads
Performnace Manifold
Headers

All Going into 1975 Cadillac 4dr

I was just going to stark working up from where I was at but didn't want to go too big on systems that would negatavely affect the carb no mater how much CID they are used on. Any other don't go over this size here or there? A bone stock 79 carb on a Cadillac has the same sizes of the 3rd recipe in the book.

Is that the carburetor in question?  What is the part number and what are the current sizes of all the items mentioned in the "recipe"?....Cliff
