What after market itake manifold would fit a four
Barrell carburtor. Is it nessasery that the adapter must be the.same as the rochestor primary,secondarys And the intake manifold... Cause thats the way mine looks stock, and when i look at the edlebrocks. None of them look the same as my carbs prime and sec

 

huh?
any intake that has a spread bore mounting pattern and fits your heads will work.. Edelbrock sells several in the Performer lineup for every stock Chevy port and bolt configuration with and without egr provisions. there is also the Performer RPM q jet if you've got the 86 and older heads.

 

The factory uses 4 holes in the intake manifold carb mount. Most aftermarket intakes have an "open" plenum at the carb mount. Assuming you plan on using your q-jet, any intake with a "spread bore" carb mount will be fine without an adapter (assuming it is made to mount to the type of heads you have, of course).
