Rochester 4G rebuild?
 

I know a lot of people rebuild Rochester Quadrajets but what about its predecessor, the 4G, that came from the factory on 327 trucks. Is there a 4G guru out there that anyone knows of?

Its been a long time but I used to do some. They are actually easier then a Q-jet. Take care adjusting the float levels. They are about like a 2GC but larger.

Give it a go. I'm putting a 2G back together this afternoon. Disassemble, match gaskets, clean, reassemble.

I've used these guys before. Very good.

Are many people still running this OEM carb on their 327 trucks? Can't seem to find much about them here on the site.

AFAIK I'm running the original carb, pretty sure it's 4G. Drove it for about 5 or 6 years after I bought it without being able to go over 45mph. Finally pulled it off and took it to an old guy that rebuilt it. Did a bang up job, got up to 70 the first time I tried, still had plenty left but I had no desire to see how that truck handled any faster than that;)

I'm interested also. I have a 4g that came on the 1958 348 big block going in the fleetside and since it'll be a milder build than the one I just completed I'd like to retain the original carb.

I have found that 5G gives me lightning fast internet access. Wops sorry wrong web sight.

I have a core at home, I may give it a go. Ive rebuilt a couple of 2 gs

Do it! My 2G was ridiculously easy. I really enjoyed it. I think I'll do the Mono on my truck, and the 4GC on my 65 Impala just to update them.
