based on visuals, it looks like I don't...
But between my last post and this one, a question occurred to me; You have a non-numbers '74 TA; You have chosen to run a '75 carb; Now you're asking about EGR/emmissions devisced under the premise that you would be hooking it up... Why? Most people defeat the emissions stuff because there is no real good reason to use any of it... I have five thermostatic valves in front of me which are (I believe) from 1973 though 1977 engines, but why would you want to have a functioning EGR if you have been running with a defeated or deleted one up to this point? Unless I have missed something, Manitoba does not have anything remotely resembling emissions inspections for vehicles this old...

Yes sorry, update:
Spoke to Cliff and he suggested the same thing. I guess we don't need it and she is running better already. I misunderstood as I thought it would have better mileage or it was necessary. I guess I could put them in for appearances sake if the price is right. Thanks everyone for your help with this - that cheby carb is finally gone!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
