i just got done pulling out the 300 I6 that was in my 88 f150 and throwing in a carburated 351w. i went to see if it would turn over and it didnt move. it sounds like the starter is engaging the flying ok but it wont budge the engine at all. i know the engine isnt sized as i spun it with a pry bar on one of the alighment pins when i had it out. my question to you guys is do you think i might just have a bad starter or do you think its a better chance that i just dont have the engine and chassis all grounds proporly attached (as i didnt take all that much time to attach the wires great).

First off get under and see if you can turn the flywheel/flexplate with a pair of vise grips, if it is an auto maybe the torque converter wasn't back all the way and isn't fully into the pump, real common prob.

If the starter is engaging that sort of says you gota ground, pull the plugs and see if you can turn it, mud.man.rj makes a good suggestion .
