engine running problem.. 402 bbc

hi guys, im having trouble getting my 402 bbc to run right.. i had the motor built last summer by a machine shop close to my town. they since closed shop and are no longer open anyways the motor is .030 bored. cant remember the heads. i think 781? they flowed similar to the 049 heads. my pistons i remember were BIG dome. i have a edelbrock rpm intake. 770 holley, headers etc

anyways the problem im getting is the engine seems to load up so bad at idle. you cant stand behind the truck at idle, your eyes burn its running so rich. when you get on the road and step it down it doesnt want to move like it should. the machine shop figured it would make good hp. cant remember the cam i have. its pretty lumpy, id have to look up the specs. we have tried diff. carbs still does the same stuff. i have a 2300 stall i believe. its been a while since i did it so its becoming foggy what parts i have with out looking.

also it doesnt want to start very good. it acts like the carb may leak down after sitting and it is flooded or somthing, you have to get your foot into it to make it start. the choke is not hooked up either. but have never had trouble with my other vehicles with that not hooked up. any help would be great! sorry for rambling on and on

this thing is just making me frustrated, im wanting to get rid of this motor if it keeps this up! thanks guys

Matt
