Well this is an old question but here it goes anyways.
I am also new to his forum and it seems like a great place to find the knowlege and experience I need.

I have a 1966 El Camino and here is my new combo:

-Earlier 4 bolt chevy 350 bored .020 with TRW cast aluminum pistons. (10.25-1 CR)
-Crane cams with a .488 lift I am not sure of the specs. I will get later
-Petejackson gear drive
-MSD probillet distributor and crane cams ignition box.
-Headers
-And of course the weind tunnel ram with two holley 450cfm mechanical choke carbs.

The car starts and idels great it also revs fine.

Here is the problem When accelerating hard at all it feels okay up to about 2200RPM then hesitates until I ease it up to about 2900RPM, then the engine starts to really pull well!

At Idle it is running really rich and I cant figure out how to adjust these damn holleys(I am an edelbrock guy)

I think I am undercammed and I need to play with the timing more.
sorry for the long post
Any input is greatly appreciated.

thanks, will
