It is equipped with a stock 2barrel Rochestor Carb.
It has been rebuilt twice and the float intermittently sticks.
I am thinking about upgrading to a four barrel carb.
I'd like to hear some opinions and testamonials.

Stock intakes from 350's are plentiful, you can also go with an Edelbrock Performer intake, it gives better air flow than stock, raised my vacuum 2". You can usually get a used one in the $50 price range. For a carb 500 to 600 cfm will be a good match. You can go with a Holley or Edelbrock with vacuum secondaries for $220-250 for a factory rebuild. You can also go with the quadrajet and mechanical secondaries, which will get you better highway milage, but the Rochester q-jet used a poor quality metal in their castings, which wears around the throttle shaft and leaks. Edelbrock makes a new q-jet, but it's around $450.

Thanks for the info. Some of this carb stuff is over my head. I rebuilt a few VW bug carbs which are a step above the lawnmower carbs I have played with. I rebuilt this rochester on my chevy truck (which might explain why the float sticks) seems easy but, I in know way know it all.
I just want the truck to run well. It doen'st have to win races, I just drive it to have fun.
What are you using? | | |

It had a q-jet that was beyond worn out. I put on the Performer intake, which raised my vacuum 2", more vacuum is good for torque. I also put on a 600 cfm Holley. I went in to buy an Edelbrock, my parts guy had the Holley on the shelf and cut the price of the Holley to match. Eventually, I would like to buy the Edelbrock q-jet, but that's down the road a ways.

It's a nice carb, looks good, tunes easy and works great. The Road Demon is cheaper than the other Demon carbs. I think it's rated at 625 or 650 cfm with vacuum secondarys and electric choke. Go for it!! | | |
