gee... i hope you're wrong on the "pulling the engine and trans" bit. oddly, the driver's side torsion bar does not go through the header and is about 3" away from the long runners. I'm thinking i will pull the driver's side head off the motor before i pull the motor and trans out. have you ever seen "shorty headers" for a 69 A-body with a 383? i tried to find some a couple of days ago and had no luck.
