What confuses me is if you ask the computer what each item adds in terms of estimated numbers, starting at around 320 as most mopar gurus say the 340 had stock, the numbers come out big, but not very accurate I would think. The carb question, sooo many different thoughts on this. I will be discussing carb size with my builder. Any thoughts on the carb are welcome, although I realize this has probably been beat to death here many times. Thanks Guys, spring is coming!!!!!
