Did you replace the starter cables when you put in the new engine?  They go bad after 10+ years, but may work fine until disturbed.  You can check them by putting a voltmeter from the starter hot terminal (where the big red cable connects) to the frame, and reading the voltage while someone cranks the engine.

Ok i will check the cables. What about me being able to crank the crank over with a wrench while in gear? And i believe my battery is dead now i dont know what would be draining it

is it spinning fast enough?
what you mean crank over with a wrench?
are you jumping the starter in gear?
are you getting power (12v) to the distributor?
are you getting spark?
are you getting fuel?
