I'm starting to plan my frame off for my 71 LS5. I've read alot of the threads people have done and there is one step that I see that most everyone has in common. I see that after the chassis is complete, most everyone has elected to build the motor next. I'm just curious why, is there a specific reason for doing in that order? I know the motor is one of the more fun items to build but if it's going to take a couple more years to finish everything else up seems like that would be the last item to finish.
