New Truck Problems
Hello,
Brand new here. Picked up a 1973 F250 Camper Special last night. Drove it home and noticed several issues and I'd like everyone's input so I can solve them quicker.
Engine fires right up, but if it's sat for an hour or so it cranks weakly. PO insists it's a newer battery.
Rough idle. Feels like engine is missing.
Sputter when first taking off, revving engine. Can't tell if it's coming from carb or exhaust yet.
Exhaust leak somewhere.
Low power. Truck has a 390, C6, 3.73 rear, and goes through all gears, but struggles to get to 60mph and sounds like it's at it's max at that point.
If there is additional info you need please let me know. I'm just looking for a starting point really.
Thanks!

One thing at a time. First, check the brakes, then go to the starting issue. Have the battery load tested, even a new battery can go bad. If the battery is ok, Take a jumper cable and bypass the battery cables to rule the battery cables out as being bad.
The last thing will be the starter.
For the misfire, I would do a compression check after the cranking is fixed, to make sure that the base engine is ok. After that, it should all be electronics.

Don's advice on brakes first (safety), then moving on to other issues one at a time is good.
Regarding the misfire/sputter issue, if it were me and I'd just acquired the truck, I'd start with an ignition system tune-up - plugs/wires/cap/rotor (and maybe points if not Duraspark?), be sure firing order and spark timing are good, etc. If it's still got issues after that, then I'd start troubleshooting from there.
