i am really not keen on a fuel cell. never had one before and want something that has a fuel gauge hooked up. the guy said that it was a 12 gallon jaz cell. would really like to sell the whole setup and get a regular 16 gal. tank. what would a decent asking price for it. my intention is to also get a 70's 350 and do a rebuild kit and put a th400 behind it. do i really need a gear that big in the rear. would like to move the car nicely but not get beat up on the mpg on the interstate.
