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 Last edited by NOrrTH; 02/23/12 03:56 PM.

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.

I have one in the garage I could measure for you later tonight, where did you reference your a and b measurements from?

The measurements came off the manufacturer's web sites but it was 2 years ago and was just reading off my notes. Last edited by NOrrTH; 02/23/12 06:41 PM.

I would think that with an air grabber on a 71 B body it would clear. all I can tell you is a member used the CH4B on his 69 road runner wit ha 440 and air grabber , the air cleaner dented his hood when he shut it because I ASSuMEd the CH4B was stock height because it is NHRA legal. I read somewhere that it is maybe an 1" taller??? A member has one on a the 440 he put in his 71 Satellite with the std. 71/72 roar runner hood and a stock dual snorkel air cleaner , it fits as far as I know .

So its exactly the same height as the Performer. I should be able to shave a half an inch off the funnel Last edited by NOrrTH; 02/23/12 08:48 PM.

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 7087044-manifoldheights.gif (227 downloads) Last edited by NOrrTH; 02/23/12 08:42 PM.
