I thought the 1980's q-jets were all electronically controlled ?

The most desirable would be the Edelbrock 1903, 1904, 1906 and especially the 850 cfm 1910.

Also the 1976-1978 M4M q-jets (on big blocks) were 800 cfm and the idle mixture screws were exposed.

The serial numbers- if you look on ebay - would be 17056*, 17057* and 17058*.

Here's a great article about Qjets that talks about the most desirable models:

Beth, I think only on automobiles, the truck ones had some kind of temp compensator or something like that. OBD 1 carbs were electronic on GM cars!!

progress has little to do with speed, but lots to do with direction
