13: Oh yes, I have spent much time pondering you spread sheet ! There is only one BB there with same c.i.d. as mine, 452. (427 with 428 crank) and he is using 37mm chokes, all larger 482's are using 40's. My carbs came with 45's which I though might be too large, but Inglese thought they should be ok, so based on that, my main jets are 180's, while larger displacements are getting by with 150-170 main jets.
to be cont.
