Okay all, I dyno'd my Barracuda,
1968 coupe, 543 stroker, pump gas- 531- HP and 597 TQ at the wheels

Fun spirted drive.

1st gear spins the tires, 2nd gear spins the tires 3rd gears makes horrible sounds, grinding, clunking, banging and then the engine just revs.... 4th goes just fine.

I think its broke. Ill pull it apart in a few days for carnage pics.
