This site is dedicated to the restoration and preservation of 1960's and '70's Musclecars. I will answer any and all questions about what is original, and what are "Period Correct" modifications. I will also post my personal opinion about what is and is not proper. People are encouraged to debate me or share their own opinions or experiences.

More Projects to avoid like the plague....
Here's some more projects that even experienced mechanics and fabricators shouldn't take on. There's a reason that you've never seen certain vehichles on the cover of Car Craft or Hot Rod or Street Rodder. A good example would be '50's Buick, Olds or Pontiac offerings. They are good-looking cars-many people think they are more attractive than the much more wildly popular '55-57 Chevys. However-there's problems if you want to restore / modify them. The first problem is until 1957 or '58 the Buick, Olds and some of the Pontiacs didn't have a modern open driveline. ( Chevys did from '55 on. ) The problem this presents is the old Hydra-matics don't shift above about half-throttle, and wouldn't stand up to even the mildest-say 350 hp-modern V8. You can't just swap in a TH350 or 400 or a Muncie 4-speed or a T10 because the mounting points on the crossmember are different and the old "Torque-Tube" driveline and huge Pumpkin rear end aren't compatible. The only alternative is to fabricate a transmission crossmember, fabricate a driveshaft, and swap in a modern engine and tranny and a '57-64 Pontiac or other similar rear end. By contrast-a '55 Chevy has a modern u-joint style driveline, and a Powerglide is the exact same length as a TH350 and has the exact same rear trans mount and driveshaft yoke / u-joint!! If your swapping manuals-the old Borg-Warner T-85 three-speed is the same length and shares the rear trans mount location with the later T-10 4-speeds. The rear axles on them are pretty darn tough-and if you "Gotta Have" a 700 hp Rat Motor-Currie will sell you a bulletproof Ford 9 inch posi rear with the proper GM mounting points. See the difference-putting a modern 350 / TH350 or even a 454 / TH400 is practically a bolt-in for a '55 Chevy. Putting a 350 / TH350 or 455 / TH400 Buick into a '55 Buick would require custom fabricated parts from the motor mounts to the rear end!! And what about body parts? I mentioned in an earlier post that it's easy to get doors, hoods, fenders, 1/4 panels etc for the Chevys, but not so for the other 1950's GM offerings. Let's say the body on your '55 Oldsmobile is really straight and rust-free. Great!! Where are you going to find taillight lenses or a grille for a '55 Oldsmobile? 1961-63 Pontiac Tempests and Buick Skylarks have the same problem. They were light-under 3,000 lbs, and they were good-looking cars. However-they had the transmission / rear axle assembly at the rear and had independent suspension. Pretty advaced stuff for 1961. However-the trannys would barely hold up behind a 326 Pontiac V8 with a two-barrel. If you want to swap in a 389 or 400 or 455-forget it. You have to custom fabricate a crossmember, and driveshaft and swap in a rear end out of a later Nova or Firebird and re-locate the leaf springs. I've seen a few 455 powered Tempests with this setup in the now-defunct "High Performace Pontiac" magazine, but not many. It's just too much trouble-most people just get a '64 and later model. The same goes for early Mopar stuff. Sure you can get anything you want if your restoring a '68 Charger or a '69 Road Runner or a '71 Challenger. Where are you going to get a 1/4 panel or a door for a 1960 Dodge Dart? Or a '63 Plymouth Fury or a '64 Dodge 330? Where are you going to find interior trim parts for a '66-67 Charger? If your restoring any Ford other than a Mustang, Cougar or T-bird your going to have some trouble. Where are you going to find headlight doors for a '69 Galaxie XL? Early Falcons and Comets make good drag racers because of their short wheelbase and lightweight. Where are you going to get a hood for a '64 Comet? Or a tailgate for the cute little Falcon-based Ranchero? The bottom line is you can restore anything you want if you throw enough money at it. But if you want to have a car that's not a money pit-it might behoove you to do a '64 GTO instead of a '63 Studebaker Avanti or a '69 Chevelle instead of a '69 Rebel Machine!! That's all I'm saying.
