Did you cut the motor with a wizz wheel or something? Remember they are permanent magnet motors.
It is a little close for the headers hopefully that will be enough. I would like to see how it works out. What about the motors are they like a drop in replacement for the factory motors? Or do they have a different bolt pattern/shaft size?
Measure? I couldn't find anything large enough so I got one that held 4 gauge and 8 gauge and drilled them out to accept the larger wire.
I miss having a garage to work in too, but that's where I keep my stuff. I have to take it to work if I want to work in the AC.
