help identifing a 67 ss 396

[akcamaro]

hi, I'm looking at a possible 67 ss 396 camaro up here in Anchorage Ak. The car has been raced and is not anywhere near original condition. the car has no factory tach, a 10 bolt, non original drivetrain, and the fuel lines have been re-ran, so no help there. The car is norwood built and theres nothing on the trim tag for an engine designation. Is there something I should look for besides trim tag/ tach/ large single fuel line/ black out tail panel that would help me figure out this cars origin? On top of all that the car is registered as a 68, and the trim tag says 68, but all the doors and fenders are 67. Did some of the early 68's have 67 doors and fenders on them? pix can be seen on the Anchorage craigslist under cars for sale. thanx
