NEED HELP! carb is extremely shot on my DD '66
Alright so the other day I had stomped on it in my '66 C10 with the factory original 283 2 Barrel v8 and it had good power for about 5 seconds and then lost all its power and wouldn't take over 1/10th throttle. Now I assumed it was the accelerator pump so I ordered a kit and took it down to the mechanic and figured it would be fairly straight forward, but it turns out a TON of junk let loose in the tank and bombed the carburetor and jets, and among that multiple parts are missing from the carb from over the years and now i either need to hunt down an original 2 barrel for parts or covert to a 4 barrel which i had intended to do down the road.
Well, I need to know, what carb is a good carb for my original '66 283? I don't want to have to put different valve covers on it for a breather, will I have to do that to run a 1406 500CFM Edelbrock? here's the 66 283 in my 1957 Chevy, it has a 1406 Edelbrock carb, but I don't want to take off my original nice Chevy script valve covers. would I have to convert with the carb you see here if I were to use it for my '66 C10? or is there a way to run those breathers to somewhere else on my engine that i don't know about? help me out here, i need my truck to get to work and can't afford a ton of down time. |

To install on a 283, get an acceptable 4bbl intake(aluminum after-mkt or original cast iron), put a pcv valve on one valve cover--any kind: nice, used ones can be had for $20--and run other end of vacuum hose to a carb take-off that has vacuum regardless of accelerator position(I use vac source on back of q'jet.); and a simple breather on the other valve cover:NOTICE: If your engine with 4bbl intake has a front tubular oil spout with a breather cap on it, the breather in 2nd v-cover can be omitted; ensure pcv-grommet fits its hole and the breather fits hole on other vc. [Plug any extra holes the vc's may have, using O'Reilly or Napa or Advance Auto rubber plugs. May hafta plug one breather tube-outlet behind the distributor--the one that used a down-pipe for a breather on older sbc v-8's. IF THIS hole has a grommet for a pcv valve, by all means use it instead of the vc-type pcv valve. Just remember, you need a pcv-valve pulled by vacuum, along with a breather-inlet to allow fresh air flow, from breather thru engine pan thru pcv valve and into engine vacuum to be burned--and design it such that it enters one side(end) of engine and exits other side(end).] I'd say the E'brock 1406/500CFM would hook up and work the same. They have a vacuum source for pcv system, and v-covers would hook up the same for breathing. They'd cost me more than a good-working Q'jet, which I can find cheap and then rebuild them cheap; plus due to scarcity of cheap 500-cfm E'brocks on used parts mkt. Then too, I hear the E'brocks are not as fuel-efficient as Q'jets. Just look at Q'jet tiny primaries vs. their huge secondaries--like cruising on a small 2-bbl and then have plenty of juice for acceleration when your vacuum calls for huge secondaries to open. On another hand: If you have to buy new, then the E'brock 500 cfm should be your cheapest initial route; and I hear they do run/perform good right out of the box, and are virtually trouble free. Whichever you get, get one with an electric choke. HTH, and good luck with your decision. Sam |

Just replace your carb or rebuild the one you have.
Look here for a carb. http://www.carburetion.com/CarbID/RochesterID.htm |
