well the crank on the engine is externaly ballanced so i have all the pulley and belt set perfect then so thats good, i'm sure i can find a 400 crank, flywheel and balancer, i will have to come up with some dough to have the block set right for the bigger crank, i'm sure i can get some 5.7 rods from something, anyone know of any vehicles that use those stock, plus i need to know how to identify a 400 from other engines, something that is garenteed and can't be messed up like numbers or something, i have like no money so all of this is going to be done by freind to friend finds and trades and work for parts type deals so i am looking to find exactly all the parts i am going to need to do this.
