Frequently Asked Questions
Coming...Q: How many L78 convertibles were built?
A: There
is no known breakdown of L78 optioned
Chevelles by body style or how many came with optional gear ratios,
etc. and will probably never be known unless we can register and document
all L78 cars sold, which isn't in the realm of possibility for obvious
reasons. See How Many L78's Based
On Body Style Were Sold? for more insight on L78 numbers vs. body
styles.
Q: Didn't all L78 cars have gauges and a tachometer?
A: No. The Instrument Panel Gauges, or Special Instrumentation, sold
under RPO U14 was always an option regardless of year.
Q: Is my L78 real?
A: This can be tricky at best.
To some, 'real' means the car has the correct and original engine it
was born with and can be matched to some form of documentation. To some,
it means if the documentation says it was born with the L78 option,
it doesn't (relatively) matter that the engine has been replaced for
one reason or another; whether by a dealer under warranty or an over-avid
enthusiast 'back-in-the-day' due to out of warranty breakage. Consider
if the car has a warranty engine with CE code or a base 396/350 motor
dressed to appear as a L78 engine, but has documentation that is original
to the car as noted by the VIN sequence and other information of the
sheet matching the trim tag.
As far as the L78 Registry is concerned, correct and valid documentation is the primary objective in the registry, not current engine.
