Thanks, guys! The VIN shows it was a V-8 for sure--Phil's explanation of the springs sagging gets rid of any 6-cyl doubts either way. As for the M-21, in retrospect it was probably retrofitted, too. The car had a Mr. Gasket Vertical Gate shifter and some idiot had mangled the transmission tunnel to get it to fit, i.e. gaping damn hole patched closed with some light tin and rivets. As for my 327/210 3-speed guess, I've never seen a 2bbl car with any manual transmission but a 3-speed and all had single-leg 10-bolts and mono-leafs. I think a 4-speed L30 car would have had multileafs and a 12-bolt, but you guys are the experts (chuckle). It's a Norwood car, RJ, but thanks for the tip. It was originally turquoise--I know because I've stripped every inch of the car to bare metal--and I found the vinyl top holes then, Phil. Surprisingly, my wring harnesses were in remarkably good shape and could be saved with some new sockets where the splices could be hidden in the tape. I had to replace or replate some of the fuse clips and terminals in the fusebox because of surface rust, but that was no big deal. The car has been a hotrod from Day One and will still be, but I've become almost fascinated with the original aspect of it. Thanks, guys!
