. . . with light blue paint, but not an SS. That was extra.
One aspect of 'restification' I find questionable is evident in that Malibu SS. The owner has gone thru the trouble of affixing '383' badges to reflect the addition of a stroked 350 engine that wasn't available when that Malibu came off the line in '67. This (tailored badging) is actually fairly common practice these days. There are several popular overbore-and-stroke combinations, such as an .030" over Mopar 400 block with a turned-down 440 crank, which results in 451 cubic inches of displacement.

There never was a 451 Mopar originally, but there's a segment of 'restifiers'* that insist on conveying actual displacement thru badges and decals. I understand the motivation, but find it unseemly. Disadvantageous, too, if you're going to race for pink slips.
(Your neighbor's SS has the same basic engine configuration as Bill's rod, btw: an .030"-over standard Chevy small block that normally displaces between 302 and 350 cubic inches fitted with the longer stroke crankshaft from a 400 cubic inch small block.)
We can't end here, though, until the obligatory . . .
