Lets jog the neurons of our memory for a moment, and a few decades.
The first car had been disposed of, while the 327 was kept for future use. Those were the days when cars were stripped of useful parts prior to disposing of the remains.
This dealer takes in a trade a 1964 Impala SS, black with white bucket seats, a tired 283, a 4 speed with the original GM shifter, and a factory tachometer on the dash. Although the front floors were corroded, the car looked pretty good, and the 4 speed made it irresistible.
Obvious no power brakes or steering, AM radio...yes drum brakes.
The perfect cars to reuse the 327.
At the time the car was not a lot of money, and it was acquired.
Obvious that all the brakes lines were replaced not to relive the experience with the 1963 Biscayne, and a stout brake booster was located that generated enough pressure to literally smoke the front brake linings.
Great now there are brakes...disc brakes were in the distant future.
The 327 replaced the tired 283, which at the time was probably rebuilt and sold as a decent used 283. The tight student budgets always generated a level of creativity to make some additional money.
Compared to the 63 Biscayne which had exhaust pipes, glass pack mufflers, and shorty under the car tailpipes. This 64 had the complete exhaust with tailpipes to the rear. Yes...it increased the back pressure but the car was quieter inside.
Surely replaced a multitude of steering parts, starting with idler arms which were a weak area.
At some point the opportunity to acquire almost new 7 inch steel (also known as station wagon wheels) wheels appeared. This provided the opportunity to have bigger tires in the rear for improved traction.
Think about this for a moment, 64 black Impala SS, a 327 with a Duntov mechanical cam, factory 4 speed, stout drum brakes, 7 inch wheels, not a bad car even if the body was corroded in the floors.
The factory tachometer that ended at 5,500 RPM was deactivated and the Sun Super tach from the 63 was installed on the dash...that 327 loved to spin beyond 5,500.
At one point an electric fuel pump made its way in the trunk (electric pumps are pushers) with a separate kill switch under the dash...great anti theft system...shut off the pump...the car starts empties the carburetor and stops. Don't ask why resort to an elctric fuel pump...its a long story.
After a short period of time the cars was no longer a daily driver and relegated to the "its a toy", it hung around for a few years, then sold to a friend of a friend.
At one point the new owner mentions "The engine in that car once I took it apart was pretty tired"....the reply "Not surprised...that engine was wound up to 6,500 RPM on numerous occasions...and never came apart"
Then "Most of the rings were broken"...reply "Makes sense got the engine used, could not afford to have it rebored and new pistons, spinning it to 6,500 in worn cylinders"
"Did you notice the heads are ported, the roller timing chain, the deburred block, the polished rods, the monster oil pump from a 427 to deal with the oil cooler, the distributor with no vacuum advance, and make sure you use points from a 478 magnum with the stiffer spring (regular point would float and misfire).
The reply from the new owner "Its still a fun car"..."I know...its a darn pity the body is corroded".
Obvious...imagine having that car today.
