Did you know . . .

Not all Chrome on muscle cars is the same. Detroit used two different types of Chrome on their cars depending on the exposure the parts would receive from the elements and the intended cost of the part. The two different Chromes used were Hard Chrome and Flash Chrome. Hard Chrome is made up of three layers of metal: copper, nickel and chromium. It's thickness is usually around 0.002" to 0.0050". Wheels and Bumpers were Hard Chromed.

Flash Chrome only deposits a very thin layer of chromium, about 0.0002" to 0.0005" thick. Air Cleaner Lids, Exhaust Tips, Oil Caps and sometimes Valve Covers all were Flash Chromed.

The Devil's in the Details . . .

Hood Pins were never an option on the 1969 Road Runner. They were included in the 1969 A39/A40 Spring Special Super Bee though.

Chevrolet called their two different 1969 Chevelle SS 396s Coupe and Sport Coupe. Prior to and after 1969 it was just the Sport Coupe

Part of the 1969 SS 396 option for the Chevelle was to include the fancier rear tail lamp assemblies standard on the Malibu

Though you see it on a lot of restorations of 1970 Chevelle Super Sports the chrome trim on the lower bucket seat portion (left photo) is not correct. It was only on the seat back (right photo).

For the 1968 Chevelle SS 396, if you ordered the base engine (325 HP) with an automatic the car did not come with the A.I.R. system. This was the only combination of drive trains to be so.

1967 was the first year the TH400 HD Auto Trans was available in the Chevelle but only for the SS396.

As you can see from the above chart Detroit was already fudging their horsepower ratings in 1963. Going from 11:1 up to 13.5:1 compression ratio on a race engine (which the Super Stock was) nets an increase of about 30 to 40 HP depending on the RPMs. The higher the RPM the higher the HP increase.

BTW . . . just a bit of trivia . . . today's modern NHRA Pro Stock car runs a CR of 16:1 which results in an increase of 150 HP over an engine configured exactly the same only with a 10:1 CR.

Now . . . speaking of higher compression ratios . . . the more things change, the more they remain the same . . . auto makers are trying to convince the Fed to bring back 100 octane gas so they can raise the CR of their engines to the 11:1 or higher. One of the advantages of higher CR is better fuel efficiency. The purpose of octane in gasoline is to control detonation.
