Just cant get it tuned right 440

I just realized that your cam is a three bolt set up, but PBM lists one for that also.

After looking at your first post again you said that it falls flat about 3500? If so I'm NO expert but I can see a couple of things that may be contributing to your woes. First thing that cam likes ALOT of compression, you are most likely bleeding off a ton of cylinder pressure with only 10:1. Second is that cam doesn't really start making power until around 3000 rpm, and most dual plane intakes I know of run out of steam around 5-5500. Next thing is your carb may too small. I was running a Holley 750 dp mech. secondaries with a much smaller cam and it wasn't enough. I have since up graded to a Quick Fuel 850 cfm mech secondaries carb, and now things are moving in the right direction.

What is the primary use of your car? Is it a street car or a race car? What rear gear do you have and is it a 4 spd or an automatic? What stall do you have if it is an auto? these all play into the big picture.

Hope this helps, I just went through alot of your experiencing.
