66 Dart GT HT Whatsitgonnabe?
So I sent a request to Hughes for a camshaft recommendation. With the specs I gave them, they recommended their smallest mechanical cam, the
STL3438AS-8.
It's a solid flat tappet 243/238 @ 050, 546/558 lift, 108 degree LSA.
I filled out their questionnaire like this:

Final gear ratio
I have a 489 case with set of 4.56 and a welded diff and a 741 case with 3.23:s and an Auburn diff. Can get any other available ratio.

Sorry, don't have that
I'm a little surprised they recommended their smallest solid cam but I suppose the small cubes would make a bigger cam lose to much low-range torque.
