    '67 C2 Big Block differences from Small Block

    Hello - I'm looking at a NOM '67 car that APPEARS to have come originally with a 427. I'd appreciate any help to make sure I'm covering all the bases to confirm whether that's really true....i.e. any additions / clarifications to what I'm considering for the differences from a 327? These are the more subtile differences I'm aware of and either have already checked or plan to check:

    The differential yokes are attached to the halfshafts with caps instead of u-bolts. I'll look for green paint spots on the halfshafts my '67 judging guide should be there, but I won't be too surprised if I can't find them. I'm not aware of any way to confirm whether the halfshafts are shot-peened or not....

    I'm planning to have close looks at the steering relay rod and frame under the steering box to look for evidence there was previously a steering damper.

    Do I understand correctly that an original rear sway bar is straight between the frame mount locations and newer replacements/reproductions have bends in them?

    The throttle lever mounted to the fireall will be checked to see of it is flat or has a rib in the middle.

    The right inner fender will be checked for evidence of holes to mount an overflow tank and hood support on the right side.

    I'll also check date codes on some of the ancillary engine accessories (alternator, distributor, etc) that may be original to the car to see if they're from a 327 or 427.

    The car does still have a protect-o-plate. I understand it identifies the original engine. Is there a code, or is it obvious? I also understand that fake protect-o-plates are out there....any suggestions how to tell a fake?

    Because it's NOM this isn't a high dollar car (and so it wouldn't be a disaster if I am faked out), but it would be nice going in to know whether it really is a big block car.....

    Thanks in advance.....

    Bob

    If the body has never been off the frame, then check the fuel line. If it has the original SB or BB fuel line, that's about as definitive as you are going to get with the original motor missing. The POP will have the info on the original configuration as well, as long as it is the original POP. Check the archives for more detailed information as this topic as been covered in depth on a number of occassions.

      Other quick-checks include the trim tag (has to be a St. Louis body), and it should have a 7/8" (or 15/16" with F-41) front stabilizer bar (SB's were 3/4").
