"Typical" lag time for engine and components for 1956 Corvette

[Edward M.]

OK, I know this questions has been asked many times in various forms, but I want to get specific here.

My question pertains to 1956 Corvette production only, and more specifically, Corvettes that were built in April of 1956.

I own # 2117, estimated build date is April 24th, 1956. Car's original engine is long gone. Car is an original Powerglide car. The only original engine component remaining is the distributor (1110872, dated 6 C 5 - March 5th, 1956). Car also has a 6 C dated 1109001 voltage regulator. The radiator is dated 56D. The rear end is dated early March of 1956 (can't recall the exact day).

So here are the questions. Without regard to what NCRS allows (the 6 month window), what would the typical time delta be between the following:

Engine block casting date for an April 24th, 1956 built 56 Corvette
Cylinder head casting dates for an April 24th, 1956 built 56 Corvette?
Intake manifold casting date for an April 24th, 1956 built 56 Corvette?
Generator tag date for an April 24th, 1956 built 56 Corvette?
Carburetor tag date(s) for an April 24th, 1956 built 56 Corvette?
Exhaust manifold casting dates for an April 24th, 1956 built 56 Corvette?
Powerglide dated components, including the powerglide adapter for an April 24th, 1956 built 56 Corvette.

Again, I am not interested in the NCRS allowable window. I am specifically interested in the date ranges that NCRS has actually observed for original cars, and specifically for April built cars?

So, to those of you that have original 56 cars (of any month of production), what are the dates for your components listed above?

What are the typical date ranges we would expect to see for these components?

Thanks in advance for your assistance in this matter.

Ed -

Can't speak to any specific supply chain anomalies that may have affected the build of an April, 1956 '56, but I'd call it normal if most things fell in within 2-6 weeks prior to the car's build date, with engine-related castings all prior to the stamped assembly date.

I owned 56 VIN 2607 for 26 years and believed the engine to be original. I no longer own it but have the info I sent to Michael Hunt for his survey years ago. I just have to find it.
