They are almost as light as a Fox Stang, make decent race cars.. The 5.0 was optional in the first couple years, had a '78 wagon with one... Bought probably four or five with the 3.3L(200) 6cyl, to resell, never owned one with the half motor... Had enough '74-'83 Stangs with the 2.3 4cyl(plus a '79 with the 2.8L V6 & a '80 with 3.3L & SROD), sure didn't want one in a F'mont... Around the time I quit "flippin" I'd acquired a '87 LX Stang with 4cyl & 5speed along with a 5 speed '86 GT... Finally gave the LX to daughter and she ran it up close to 200K mi before buying a new Saturn... Sold the GT to guy up in OH...
