battery problems
My 272 usually starts fine hot or cold. But it does seem to catch a little quicker when it is cold. I don't know the amps on my 6-volt battery but it is what they list as a "Group 2." I used to run a group 3, but it seemed a little small and weak. Good luck, John

battery problems
Flatheads are notorious for vapor lock when hot as well as an old coil acting up. Coils break down normally with age and heat is a major problem. I remounted mine well above the usual head location allowing air circulation under it. (On a 53 Vicky).
Vapor lock can sometimes be cured by using a double action fuel pump as well as locating all fuel lines well away from heat. An electric pump is another "cure" but this requires a pump and regulator set for 1.5-2 lbs max pressure.
As far as 6V is concerned it is imperative that the starting system be as new or better. This means new 0 or 00 gauge cables, perfect grounds as well as shortening up the battery ground path when possible. Many reroute the ground path and now go from from the battery to under a starter bolt and then to a shiny frame location. When I redid my 54 F350 it made a world of difference.
