Title: ID a Q-Jet from a picture
Post by: trotterlg on October 08, 2012, 03:33:06 PM

Picked this up for a highly modified carbed 3.1 V6 Chevy, aluminum heads and 12 to 1 compression with a big cam.  Now I am wondering what it is.  Says for 81 to 85 Chevy.  This is the link to the auction.  Thanks, I am on at the Fiero Forum but I think you guys can probably tell me a lot more until I can touch this thing.  Larry

 According to my manual:

 It was used on '80-'84 Chevrolet All/Trans C, G, & K Pickups and P25-35, Exc. California, 327cid & 350cid engines. There are too many to list, sorry. Of course, by the part number, it is a reman unit.

Fast work, thanks, is it worth $45.00?  Larry

I would avoid anything commercially "remanfuctured".....Cliff

I know the PWM signal into the EMC connector on top is about 10 HRZ (10 cycles per second) but I don't know the voltage level of the signal.  Like, is it a 5 volt square wave or a 12 volt square wave?  Larry
