I have spent tons of what little free time I have getting this car cleaned up to show at the mecum survivor show, and it was rained out for the folks not registered (i.e. me). I never knew the carb on these 340s were 800 cfm, and also kept the fuel up to 20 degrees cooler than the previous yrs carb. I think the carbs on my 65 vette and the 69 camaro are 780. Who would have known. The car actually is pretty quick. Major changes were the original gas tank had to go, and ended up swapping the carb and radiator off my other 71 cuda.
