Well i recently put a rebuilt 350 in my '61 Suburban. It has a high rise edelbrock intake, a Holley 600 4-barrell, and Delco Remey distributor. I am currently runing a brand new stock fuel pump. The motor starts and idles like a dream. however, when i put the truck in gear it stalls out immediately. I have the timing advanced quite a bit (close to 20). Everything is new other than the carb. Could my problem be there?????
