Odd stalling problem

[moto916]

1974 Charger SE 360 all orginal.  Car always ran sluggish until fully warmed up, then fine once warm. Since I moved, when I take the car out before full warmup, it will stall if my first few blocks are uphill. Starts right back up no problem.  If the first few blocks are level a bit sluggish, but never a stall.  Once warmed up fully, runs like a champ uphill or down!! HaHa! any ideas?  Thanks!

I would say carb issue.

Still have the original heat activated choke on it... it's baffed and needs work, that or you moved to Ontario where it's currently -5C !
