Cab you once made a snide remark about not reading technical manuals...I have the Carter books, and I have the FSM. So I think you need to go back and look at those FSM.
I think my remark was about Chilton, Motors and other automotive service manuals specs, Not about the original F.S.M. manuals
On your deal you need to test, test and retest to get the best jetting for your carbs. using the fuel sold in your area
I had one set of 1966 or 1967 visually modified Hemi carbs that ran better than any other set we had, I traded them off to a guy who had a set of 1970 Hemi carbs on his 1966 or 1967 Hemi GTX because NHRA back then, 1973/1974, require us to have the factory carbs on the cars we raced in both Stock and Super Stock.
I was racing a 1970 Baracuda back then with a 426 Street Hemi motor in it (not a original car)and had been tossed out by NHRA tech due to having a intake manifold that had been bead blasted inside at the 1975 Winternationals
I had thrashed to get the car put together in November and December of 1974 and knew it was illegal but forgot to change it before going to Pomona for the 1975 Winternationals
