**73 Scamp Mini Pro-Street Engine Swap**
I'm surprised you don't like the coilover front suspensions, they free up so much room for headers and stuff. Is it because you weren't getting enough front end travel?
I'm hoping that new converter works for you at the track but it doesn't sound like it's built right for your combo, if it slips to over 3000RPM's just trying to get the car to move.
