4500 top, The standard drag pak manifold does not have enough meat at the top to support a 4500 pattern.

So are you saying the 4500 casting has a larger dimension (shown in red) on the outside then your 4150?

Or the Mopar Drag Pak intake?



The intake casting can accomodate either 4150 or4500 carb. And,yes the intake is physically larger than the Drag Pack intake in that area. The DP intake doesn't have the material to be opened up for a 4500.
