First remove spark plugs and squirt a bit of oil in each cyl. If it's free, will turn easily by pulling on the fan belt or if flywheel is in place you can try to move that, prying with a screwdriver against the bell housing. 235s won't have a bolt in the balancer like a V8 unless someone has drilled crank. No problem using a truck motor for you, front mount can be used if it looks just like your old motor. Good luck
