Pokey Posted December 24, 2006 Report Share Posted December 24, 2006 Do you know the year of the motor it came off of??? I remember that quads from 350's were in the 795-825 cfm range (at least the 4-barrels were). They were huge, but sucked ass for carbs. Is it a 2-barrel or 4-barrel???

Guest beatitouttheframe Posted December 25, 2006 Report Share Posted December 25, 2006 its off of a 86 and its a 650 i think and it a 4b Quote Link to comment Share on other sites More sharing options...
Pokey Posted December 25, 2006 Report Share Posted December 25, 2006 Even if it's off an 86 I think it's still bigger then a 650. I think it's just running to rich and the A/F ratio off a bit and that's why it wont run correctly. I thought 85 is when GM introduced TBI to most of their cars...My mom had an 86 K-5 Blazer and it had TBI. Quote Link to comment Share on other sites More sharing options...

Pokey Posted December 25, 2006 Report Share Posted December 25, 2006 I don't recall a quadrajet ever being that small, but I could be wrong. I still think it's throwing your air/fuel ratio way off and running too rich. I have no idea how to tune a quad, so I would say try to find someone with either an Edlebrock 650 or a Holley 650, borrow it, and see what changes. Also see if they can tell you what size your current carb really is. I can look it up by a number on the carb using a Haynes manual. Check the carb and give me all the numbers on it and I'll see what I can come up with. If it works out to be fine by using either one of those carbs, get one. Edlebrocks are great for street use, but if you plan or doing any kind of racing, ever, go with a Holley. Quote Link to comment Share on other sites More sharing options...
