Switching from Volvo TBI to Carb on a 1996 5.7 GI

[Scott06]

Follow up after putting 30+ hours on the new setup. The 5.7 runs like a top with the new Edelbrock 1409 and Walbro fuel pump. I’m guessing my fuel burn is around 10 gallons an hour running at 3000-3100 rpm 26 mph. So far so good. Again a big thanks to all the helped out!

nice I prefer carbs for these applications exactly for the reasons mentioned.

I keep a carb kit for them on hand, but havent had to use it.

Did you have to change jetting on it for the 5.7? On my 5.0 only thing I had to do was tweak the accelerator pump nozzle and linkage. There was some slop in the linkage that lead to a lean spot on holeshot. Spent time messing with jetting, later put a AFR meter on it and saw it go way lean for quite a time, then swing way rich as i had 2 wrongs trying to make a right. I think I ended up back at stock jetting and step up rods just a bigger accel pump nozzle and bend the linkage so it was under spring pressure from the pump all the time.
