Gear split

I would think the wider your powerband between peak tq and hp the more split
you could tolerate, with that being said its still some trial and error as some cars fall
back more on the shift than others. converter, rear gears and weight all come into
play but i think your big block may tolerate more split than a low tq small block.

We currently have two E/SA cars.....71 Dart 340/314 and
73 Plymouth 440/345. Both have very aggressive cams in duration @ .050 (265+) and very close lobe center (106). I do not know what is normal because
we march to beat of our own drum around here.

As different as they are they both like 2.75 low and being short shifted
out of low ( 400 - 500 below 2 - 3 shift. Hopes this helps.
