Quadra jet manufactured by carter???

[72jrfan88]

Hello all. My monte has a 350 with 4brl quadrajet. Mine is stamped "manufactured by carter" on it. All the numbers are present and decoded it to be stock from what I understand. Anyone know about this and is there any differences from the one rochester makes? It is almost like carter helped rochester out at some point. Any ideas are appreciated

Quadrajets were produced by both companies for GM

Hey Eric, I recall reading somewhere in my Quadrajet research that Carter was basically contracted to help with supply issues as Rochester couldn't keep up with the demand. Are they exact copies, I couldn't say...........

Sam and Murphy are right. I have a great book about Quadrajets. In the late '60s, the Rochester Products division of General Motors wasn't able to keep up with the production demands. The Carter Corporation was contracted to meet the demands and their carburetors are identical to the Rochester, other than the name.

There was also a period of time here recently when Edelbrock was making them as well. I think those may have some engineering "improvements", but were manufactured using the original tooling.

The Edelbrock Q-jet was meant to be an aftermarket performance upgrade for people looking to replace their tired original carb. I find it interesting how long the design was in use.
