it bolted together and yes im using the torque converter from the 250 but i dont think that has anything to do with the problem
Could it be that the engine from the 85 F-150 had been swapped out prior and they put an older (28 oz) engine in it? I have seen this many times. Then when you put the 50 oz flywheel on it is where the vibration came from.
ok so today i took my car in to my uncles shop to put it on the lift i removed the oil pan and so that the crankshaft was 50oz so since i had already replaced the harmonic balancer i knew that wasnt it so i procceded to remove the starter so i could see the serial number on the block and i decoded it and its from an 86 so then i removed the flywheel and it wasnt a 50oz!! apparently my dad bought a 157 tooth flywheel but not a 50oz!!
