Hey welcome to the forum. I won't be able to help you much with breaking down casting numbers but I'm sure there's plenty of others on here that can. What kind of motor is it? (Chevy, Pontiac, Olds, Buick?) I'm sure you know this right, you'd pretty much have to to be able to buy anything for it. Pictures are always nice and in a motors case sometimes help, alot. You'll find lots of good info on here. Let's start with that. Also what have you done to it? Does it run good? Do you know what transmission you have (OD?)?
possibly could use a carb kit??? A fuel filter is also cheap and worth trying. Has it ever ran better and had more power or has it been that way since you got it? I'm assuming it don't have any emission stuff anymore...right? Otherwise maybe a vaccum leak/problem.
ok does anyone know where i could get a cheap carb...like maybe on the site? its only a 450cfm quadrajet thats on it now... the guy i bought it from says its has 380-400 hp but the way it runs it dont even have one lol i cant even get it to break the tires 
Sounds like who ever timed and "tuned" it for you missed the carberator. haha. Factory Q-jets are factory rated at 750cfm and 795cfm commonly known as an 800. Sounds like you need to have your carb worked on. Search the yellow pages etc for a local carberator shop or rebuilder. It may not need a total rebuild but it sounds like it needs worked on. This will probably be better and cheaper than buying another new carberator which would or should still be tuned by a professional or someone experienced for your motor/car anyway.
hey when i timed it it was way off...the cam and crank were so far off i was supprised it even ran...its timed right on but it think ur right on the carb...ill try to find someone round here to rebuild it if i can...OH YA i found three gp in the scrap yard up here!!! ill try to get pics of them and see what all is good
