How tall is a CH4B? vs other intake heights.

Where does the CH4B fit in below? I have an AirGrabber and the regular Performer rubbed the air cleaner lid on the hood. My builder prefers the CH4B over the Weiand, but I dont know if it will fit.

So does anyone know the car pad height for the CH4B?



Stock a) 3.33"

Weiand Action + a) 3.25 b) 3.69

CH4B a) ? b) ?

Performer a) 3.8" b) 4.8

Street Dominator a) 4.13 b) 5.25

Performer RPM a) 4.9" b) 5.8


Thank you

Its a '71 GTX and I definitely had clearance issues with the Performer - no carb pad.

AFAIK the only aftermarket intake that would fit would be the Weiand as its even lower than stock.

I'd like to get an exact carb pad height for the CH4B to know how much of the horn I can cut off or if I can even use this manifold.

Thanks for your help guys.

Sure, thank you.

a) = front of carb pad and b) = rear of carb pad.

The measurements came off the manufacturer's web sites but it was 2 years ago and was just reading off my notes.

Stock a) b) is 3.4 and 4.2

CH4B ia 3.8 and 4.8

Actual difference between stock, and CH4B at the midpoint is between 3/8 and 1/2 inch

TY TY... So its exactly the same height as the Performer. I should be able to shave a half an inch off the funnel

Do you know where they measured the carb pad to? Top of the block I take it?

Yes. From Edelbrock's site, they take a straight edge and lay it along the carb pad front to back. Then they stand a ruler from the bottom of the front of the manifold and see where it meets the bottom of the straight edge, thats "a". ...well here's the picture
