have documentation on the origin and sale price. Check the numbers twice. The VIN numbers are
located on the back of the engine block, on a flat spot between the heads and at the apex where the bell
housing meets the block. Some solvent or WD-40 can usually clean this area off enough to see the
numbers. The Serial numbers on the transmission are typically stamped on a flat spot on the bottom of
the housing near the middle of the transmission. Some G50’s have an 8 digit code (i.e.: 1987 G50),
while others have a 12 digit code (i.e.: 88-89). The first five digits in the serial number (see the table
above) are what you will need to reference what the transmission has for gears, 5 or 6 speeds, and what
model Porsche it came out of.

The easiest way to avoid engine work is to buy a donor car with an engine that runs. Everyone will tell

that gets taken out. A battery also helps when some guy says, “Don’t worry it runs great, but since I
don’t have the battery you’ll have to trust me.” The Corvette is computer controlled and should run
well the first or second time it is turned over. If at all possible, put the car into the gear and drive it
