Hello I am new to this so I hope this is in the right place...I recently did a c4 to t5 swap in my 67. I used mostly parts from modern driveline and after putting the motor and transmission back in the car it will not crank. Also while out I replaced some thinkg on the motor such as timing belt cover, harmonic balancer, crank pulley, valve covers, and pulley's. When you turn the key it just clanks like it is bound up. Removed the starter and tried to turn the crank by hand and it will not turn. Removed plugs and I am still unable to turn the crank by hand. Any help would greatly be appreciated. Thanks
