hi everyone! im very excited as ive started making my engine bay and engine look a lot better. recently i pulled off the carburetor for a rebuild because of my header problem(cherry red header) and because its old. so when i pulled off the carb i also pulled off the intake manifold. i started cleaning it up but i wanted to ask if i needed the black plastic cap with the 5 vacuum holes in it. heres a pic.

 

o and the other pic is a little taste of the first of many cleanings i will perform

 

Yes you need it.

 

Not only does the phenolic spacer provide vacuum sources, it also has a bridge between the front and rear rotors, and provides a thermal break between the engine heat and fuel in the carb.

 

ok, i just wanted to know, but if i go with weberes or holley obviously i dont need that right?

 

If you go with a Weber or Holley, you will need a matching intake for either.

 

+1

Also it acts as a physical spacer. Without it the carb linkage will bind and the studs are too long to clear the base flange. Basically it wont even bolt on without it.

 

ok thanks guys ill postmore pics of my progress in the engine bay and engine later on.
