Ford 8LX GT?

im so frustrated!! i cant get this car to run right......ive changed the plugs, wires dist. cap, batt., valve cover gaskets, air filter, thermostat, upper and lower radiator hoses and some exhaust work--------NOW when it get heats soaked it wont start back up up (hence the batt) but i soon found could tell it wasnt the batt.----dont know what causes that-----AND if i run it in town for longer than an hour it gets hott-------I also put that sea foam in it to help, forgot that----------Anyway its still clackling at around 35 3600 RPM when trying to accel---I dont put cheap gas in it--------I got no horsepower, i mean id be lucky if i was getting 150hp out of it--------OH yea its smoking now too-----ALSO rem i have no money!! lol
