Carb recomendation for 77 almost stock Silverado
I've had an on going issue with my truck when it sits for a few days it won't start unless I prime the carb. Also once Theits warm and sits for 45 mins or so, it will start and immediately die. Then it has to turn over 8 time-ish before it will start. The carb is a stock 4 barrel Rochester. I put JB weld on the plugs that normally leak many years ago. I'm assuming they could be leaking again(?), but I think I want to look into alternative carbs without this issue.
It is a 350 engine bored 0.010 over with an RV cam (whatever that is) and the metal line between the carb/fuel pump has been replaced with rubber fuel line with inline metal can filter.
FuelFuel economy is important so in addition to new carb I'm thinking about replacing the turbo 400 with a 700R4.
Any comments/suggestions are much appreciated!
Thanks,
Pat

I would replace it with another Quadrajet, don't think anything is going to give you better mileage. If you want to get away from the Rochester, maybe look at a spread bore holley.

I had this site bookmarked for my 68 El Camino Rochester. I have not used them yet, and forget where I got their name, but maybe they could rebuild yours. Always nice to have the one you started with IMO.

Glad you checked Poodle. Don't know where I heard of them but reviews are always important to consider. A personal reference is golden. Maybe someone here can steer both of us to a good carb shop. Keep us posted on your progress!

I used them to locate a kit for an oddball carb several years ago. Recommended them to a friend at work when he needed the carb on his Toyota pickup rebuilt - I can’t recall what they charged him but the work was guaranteed for life. He got it back after a couple weeks and said all he had to do was bolt it back on and the truck ran great.
I haven’t needed to use their services since but I do remember them as being very professional, courteous, and kept me up to date when there was something to report.
