i have a racing beat intake manifold for a holley but they told me it was for a 4port 74 13b, i want kno if this could work on my 12a, cuz the setup i was doing was 12a irons and gslse housing with 91 rotors, but im not going for that setup no more

 

bump come on some one has to kno

 

The intake woulda worked for the setup you were gonna use. It won't fit a 12a, seeing as the 13B is longer and the holes are further apart.

 

thanks
