360 start up problem

Try pulling all the plugs and shooting some oil in each cylinder and see if it turns easier.Is it a high compression motor?The best thing to do with a stored car is to pull the dist. and oil pump shaft,use a rod to turn the pump clock-wise to oil the bearings.

i agree . take the starter out, take the belts off and get a socket and wratchet on the crank bolt and spin it around by hand while shooting some oil in each cylinder until it feels free, and inspect the torque converter / flywheel while turning it. bench test the starter to make sure it is working properly.
