I'm not planning on making it a high performance car. I"ll leave that for the muscle car owners with the thick wallets. I picked up the OD for a song, and can't see dropping a $1.2K 833 non-OD tranny, and/or for that matter, a $2k 8.75" SureGrip into a lowly stepchild Valiant. My goals are for it to look respectable, sound sweet, enter car meets, and maybe a PowerTour someday.
