Excellent keep the barn posted on progress.

The 48's are a bit bigger than the 97's - which is why I'm giving them a try. To me, the bigger issue is the design of the early EM manifold - probably isn't going to make much of a difference which carbs you run (I'm doing the same thing, original EM manifold of the same design).

Just for the heck of it, I'm going to put my car on a chassis dyno and screw around with a set of 97's, 48's and Holley 2110's (probably what we both really need). I'll also port the EM manifold and see if I can improve the flow.

My guess is that I'll see very minimal differences between all three sets of carbs - but what the heck, will be fun to have some REAL numbers to share!

Take care . . . ping me if you need additional information.
