I have owned my truck for just about one year now, and while progress has been slow, it has also been fairly steady. When I got it the original monojet on the Chevy 250 was toast. The auto choke was gone, and it had some other problems. Cold startin sucked! I replaced the carb with a napa remanufactured monojet with manual choke. It turns out that they gave me the larger 292 carb. It had a good cold start, but you had to let it warm up for about 5-10 minutes before driving. It worked good in general, idled smooth, had good acceleration, and got 16 mpg on the hiway. My only real complaint was that it stumbled a little (had a "dead spot")just off an idle.
I ran the Monojet a short time then heard rave reviews about the Holley / weber 5200. I bought a weber and an adapter from Langdon's Stovebolt. It did nothing for performance or gas milage. The only real improvement is a really smooth low end, and incredibley good cold starting and driving. I have never been able to get it to consistently idle smooth and I hate the ugly freakin' adapter.
SO, I'm getting read to rebuild the 250, including mild cam, port work, mill the head, and 1.6 exhaust valves. I am also going to work the stock intake and exhaust manifolds over so they match the ports on the head, et. I want to use the biggest and best one barrel I can. I love the elegant look and the simplicity! However, I am having a hard time finding good info on one barrel carbs; ie, ventura size, flow rating, et.
Now, here's my real question: What is the best one barrel for my application, and why do you say it is the best?
Excuse me for spamming the board, but I'm trying to find some answers.
