Finally got my Mustang moving. Had my C5 rebuilt with a shift kit, everything lined up nicely this time. Engine actually revs lower when I put it in gear. And for the first time in about 7 months of my first engine/trans transplant, the thing actually moves on its own.
Dad's jaw dropped to the ground when he pulled in yesterday and I drove it to the top of the driveway. Then he got a little T'd when I gunned it and left a 2 foot trail of sweet n' sour smelling rubber on his driveway. I know, I'm bad
But I'm happy
Thanks for all your help and advice everyone. Bars open, drinks are on the house tonight.
