I got the numbers off my q-jet and they are as follows: 7943240 Im not 100% sure of the numbers because the insulation of the hood decided to make its way all over me. :laugh: ou: Can anyone tell me what the numbers represent? o No: Thanks :TU:
Probably 7043240 which is a 1973 Buick 455 with automatic transmission..that's what those numbers would mean.
Your right it was 7043240, I just had to clean it a bit better. What does the "LA" stand for after it? Thanks again George and Smokey. :TU:
LA designates the engine set-up, 49 state emissions or CA emissions. I think it may also designate other info but can't remember now.
702 and 703 as first 3 digits was used in the 60's 704 was introduced in 1970, and as you can see with all numbers: The 4th digit represents the model year. Click here :Comp:
Just out of curiosity, does anyone have that carb list filled out with CFM #'s for the 4 and two barrels? I know there 800 Q-jets, but does anyone know what flavors the two barrels came in and also what CFM the Q-jets for the 350 were? Thanks!
Thank ya sir! :grin: Anyone have any ideas on the old 2Jets and 2GC's for flow numbers, too? I'm thinking multi carb setups on those. :laugh:

By the way when did GM go to that Quadra Jet with the electrical plug on the top of the carb and what's it for anyway? Dave B
As far as I know the plug in on top is a throttle postion sensor and was used in the late 80's STAY away from that one it was the carb used just prior to fuel injection Ken
