School me on SS427s!

These cars can get real complicated and confusing. Now that black '67 just posted above is a 1967 Impala SS with a 427. It is a much different animal than the '67 SS427. Although both models were 427-385 HP motors with L-72's being optional. Those '67-68 SS427 cars are really neat, neat cars that have been over-shadowed for a long time. Lots of very cool features on these cars. The '69 cars are alright but they they've always looked to me like somebody added the SS emblems to make a home-made Super Sport and just don't have the appeal of the '67-'68 cars.

I used to classify cars like the black one from SS427's by calling them 427 SS cars..but that just confused everybody. So now I call them Z24 cars and non Z24 cars.

The SS427 option was merely a trim package, just like a Judge, RS, SS396, etc. It was a separate option costing about $95.00 and got you the special trim, bright engine accents, F40 suspension, redlines(or white), and automatically equipped the car with a 427. By the body numbers it wasn't technically ever it's own "model", but in the literature it is classified as such, the same way a regular Super Sport was in 68.

What a lot of people don't understand is, you could purchase an Impala Super Sport with a 427 or you could order an Impala with the RPO code Z24 and get the "SS427". Two entirely different cars so to speak. The SS427 carries a lot more mistique than a 427 equipped Super Sport as their hoods and badging had a lot more appeal.

Mark, I am pretty sure the L72 was not available at all in 1967 Impala....

am I wrong ?

You're correct, until one of the supposed few that were produced turns up lol

I had one when I worked at Chevrolet Engineering - tagged it for employee purchase the day it arrived in the Company Car Fleet garage; L-72 4-speed SS427, special-ordered by Engineering for Chassis Development. It hit the 3,000-mile mark in December, and I bought it and drove it home just before Christmas; sold it in Flint a couple of years later.

Removed the "Special Order" tag from the left side front fender reinforcement and put it in my rollaway just before I sold it, still have the tag - photo below. There may not have been any L-72 SS427's built on dealer order for retail sale, but there was at least one built for Engineering; I bought several sets of rear tires for it in the two years I owned it.

John,
Do you have any memory of a red 68 Biscayne 427/385 stick ordered by engineering to test posi clutches? I was talking to a guy who bought this car from Chevrolet after it had traveled in circles for 3,000 miles worth of testing!

[Paul Vitale]

John was it a 67 with an L-72 and do you have anything documenting the build ? Iam sure you have had that question asked of you alot when you talk about that car LOL ..
