What is the best manifold available for a quadrajet with EGR? I have a CCC on my car with the EGR blocked off, but need the EGR to pass emmisions. What is the best choice if EGR must be retained? I beleive I am limited to the Performer. Motor is kept to 5500 rpm and below, but I feel that I am pushing that range with the performer. Any suggestions on the ideal manifold for my 350? I plan on ordering this weekend as I have an entire winter break to finish a few odds and ends with the car. If I have to pull accesories off to change the intake, Im gonna change the water pump at the same time, so Id like to get it done soon. Thanks guys.

 

I'd recommend a ZZ4 one. You can find them in the classifieds on this site all the time.

 

Isnt the ZZ4 on aluminum vette heads with the new bolt pattern though? I have 1971 heads, will it bolt right up or is it the 87+ pattern?

 

Bolt Holes

 

Exhaust Crossover...

 

Exhaust Crossover, take 2....

 

Part Number....

 

So I take it it'll fit pre 86 heads then?

 

Just got my ZZ4 intake in, will install soon, too bad I just broke a valve in the motor

 

I looked the ZZ4 manifold up in my GMPP catalog. It is for small blocks up to 1986. It is a better manifold than the performer.

Good luck
