[68Gold/white]

I do not care for lowered pickups that go much more than an inch or two, especially chopping the frame, and ending up with the body sitting as close to the ground as most cars, just not MY deal.

5 spoke American Racing wheels would look great, and go with the year of the vehicle, either the polished ones or the ones with the gray or black centers that have the polished aluminum rims...

That cast iron intake in the tote, gives up nothing to the intake on the engine! The original quadrajet would work well, but later quadrajets are better, especially one with an electric choke.
Beware any carb needs to be tuned to it's specific engine/purpose. The E-carb on it now might run and drive OK, but I'd bet could be improved upon!!!
IF, IF you go the quadrajet route, you need to contact Cliffshighperformance.com for parts, advice, or possibly even a carb, only way to go!!!

One or two inch lowering blocks on the rear would level it out a bit. I would not want to do anything more to the suspension, again, just my thoughts....with my 68 was half as nice as your's!!!
