I figure right now it might be just because my truck is cold. But when slowly acclerate from a stop the truck will start seizing and choking, if I keep my foot on the gas it'll die. If I take it off, it'll be ok. But, if I floor the truck from a stop it'll be cool and be good for me. I'm wondering if this could be anything else other than just a cold start. It seems to run alright and be ok when it's warmer. I was also thinking the choke on my carb. I've got a 351 H.O.

Normal tune up checks are in order. Sounds like it could be a weak ignition system. They can act rather strange. In my camaro, a weak (but brand new) ignition system caused similar problems. Turned out to be that I needed a stronger aftermarket ignition module instead of the cheapest they pawn off at Auto Zone and Pep Boys.

If I remember correctly, the mixture is richer when cold, so that would make an added stress on the ignition system.

Check for thermostatic choke adjustment problems too. Aging bimetal in the choke i.e. rust and corrosion of the bimetal coil will cause the coil to thin as there is less integrity to the metal thus being more sensitive to temperature changes. My 69 caddy had this happen and every time it got cold the choke would open too much too soon and basically starve the engine because of increased air too early in the warm-up period. It boils down to replacing the bimetal coil if it has rusted too much to correct the problem within normal choke adjustment procedures.
