Like this. This is for a big block Chevy. Finding even a picture of one for a Mopar is hard now. If yours looks like this, it's a damn good one.

The top on the edelbrock base is my favorite top for that.

When I was way younger, and more motivated, I was going to take a slitting saw to that top on the W2 intake. Then I was going to reduce the plenum volume some and then (remember...I was younger and much more motivated back then) I was going to shift the carb mounting pads a bit.

Yup. I was WAY more motivated back then.
 
I think the MP’s plenum is a bit generous.
But it’s a race part.....

Do you recall what cam was in that 318, if other than stock?

It was a factory roller cam motor with 360 valved ,ported Factory 302 heads and a Comp Cam, 480 lift, do not recall duration at this time.

Would the 500 cfm Holley two barrel carbs they use on circle track motors be a good candidate for a dual tunnel ram? Should be tunable and not break the bank. Definitely not as sexy as dual fours though.

My brother is running a pair of them on his 52 sedan delivery. Goes like stink and has absolutely no bog to it at all.
 
I pull the carb off?

Yeah its more of a pain in the *** but it really adds about 5 minutes so i just deal with it.
 
I may be wrong but on my big blocks
Moderate compression big duration
Cams run better with low cfm mechanical secondary carbs. No vacuum.straight advance + little nos
Dont ask me how I know.
