Thanks Gofast! I was told it was a 700 with 750 boosters. I really dont need a 750 on a 351C. But I dont think it will hurt. I was trying to figure out what was inside, before I had to tear it down. I'm getting a pop out of the carb, sometimes followed by a puff of gas, when comming off the line. I checked the timing and it's fine , not a backfire. I thought it might be that the carb was running lean causng the pop. Any thoughts or advice would be appriciated
