Hey, sweet, that's an early-production V200 (the inner trim ring on the "spare tire" trunk lid was deleted early in the '60 model year). Not super-early, though, because you haven't got the "shark fin" atop each front fender, and not one of the first ones built, because you haven't got the stainless steel trim around the windshield and backglass.
Be very careful before you decide to spend any money with Clifford. They have a long and ugly reputation for being a bunch of clowns; see for example
here,
here,
here,
here, and
here. Much of what they sell is inaccurately described, and a lot of it is not even slightly cost-effective. The good news is that you don't need to go to Clifford to get hot rod parts for slant-6s; there are lots of other, better options. See for example
Dutra Duals and header options discussed in
this thread and
this one,
Erson custom cams,
HEI ignition upgrade,
1.6-ratio rocker setup from RAS,
Mike Jeffreys windage trays,
Hurricane intakes,
other exotic intakes. Hi-perf engine buildup

this thread, and remember it'll need a
valve adjustment.
