Is this a 57 distributor?



It’s in my 56. Is this the correct engine ID code for a 56 v8?

Pappy is right 57 is the first year of the door on the dizzy cap...

There should be a plate rivited to the side of the dizzy with a number like 1110874 or 1110890 stamped in it for 57 model...

56 was 1110847 or 1110866

56 Corvette was 1110860
57 Corvette was 1110891

On the engine code the first letter F is the plant Flint, the next two are the year 5?, you need to try and make out that second number it could be an 8 but I can't tell I'm sure it's not a 2 since they didn't build smallblock V8's in 52... Haven't found info on the last 2 digits yet but I'm sure someone will...

Thanks for the numbers I will try and find them tonight

I found this site on engine codes
http://www.nastyz28.com/chevy-engine-code-stampings.php
From that site it looks like it was made in Flint on May 24th and the last F is for one of the two combos below
F 1955 265 Powerglide - 2 car
F 1957 283 Powerglide - 2 cars & Vette

Does any one have a 56 with suffix code of F or was this an engine swap?

That works on newer engines but in the 50's the codew were different..

Some very early smallblocks from the mid 1950 model years had an Engine Assembly Date which only included the last two digits of the year. It might look something like "F56FG". On later model engines the engine assembly code looks similar to this "T0422TR". In this case the first letter "T" stands for an engine factory Tonawanda. Your's might have an "F" or "V" for Flint, MI. The next two digits stand for the month of the year, in this example "04" or the fourth month April. The "22" stands for the 22nd day of the month. So what do we have so far in this example? The motor was assembled at the Tonawanda factory on April 22nd. The years are not given. In the 50's and 60's, Chevy used a Roman numeral " I " for the number " 1 " in these engine assembly dates. Don't mistake this for a capitol letter "I". What we have left is the "suffix code" which in this example is "TR". Chevy used one to three letters of the alphabet to code the type of engine, transmission and vehicle into the suffix code. In later years, parts of the Vehicle Identification Number (V.I.N.) were also added before or after the Engine Assembly Date/Suffix code. In that case you might see "T0422TR 1123456789" stamped into the pad on the front passenger side of the block. Sometimes the engine V.I.N. was stamped into a different area of the block on the flange edge of the rear of the block, near the bellhousing mating surface. Sometimes the stamping is found above the timing cover mating surface on the front of the block.

So it seems the way to tell depends on when they changed the way the codes were stamped...

The casting # on the block might also help, it's on the driver side top of the block near the firewall...

I might have to invest in the Chevy By The Numbers code book...
but I prefer free info over buying it... lol

Can you tell me where you got the reference that says 1956 Corvettes used a 1110860 distributor?

All chevrolet distributors from 1955 to 1959 were manufactured by Delco - Remy Division of General Motors in Anderson, Indiana. There were two plants invilved in producing ignition components at Delco - Remy:
Plant #10: All convential (point type) distributors and ignition coils
Plant#6: All ignition amplifiers and capacitor discharge ignition systems.
All dizzy`s were cast iron until 1962 when die cast was introduced.
All delco - remy had model numbers attached to them but varied their location from distributor to distributor.
1955 to 1956 - mdl no. found on oval delco remy tag riveted to outside of distributor housing.
1957 - mdl no. the process changed through to 1974, all cast iron non dual point distributors used a small aluminum band which wrapped around the top of the distributor housing.
All 1957 to 1961 dual point dizzy`s used an oval delco remy riveted tag.
So 1956 dizzy no`s are for passenger cars 1110847, 1110866, 1110869, 1110872, 1110879.
Corvette 1110872, 1110879,
Canada passenger cars 1110847, 1110866
Engine block 55 was # 3703524 block 56 was #3720991 block57 #3731548
Date code flint example: A 8 5 A=Month:January 8=Day 8th day 5=Year 1955
Tonawanda example: A 8 55 A= Month:January 8=Day 8th day 55= calender year:1955
Keep in mind when checking date codes of specific engine parts, alway remember to verify the the built date of your car, engine components should generally be dated one to three months prior to the car built car.

I would have to say no because a 265 in 57 used 1110874, 283 used 1110890 and corvette used 1110891. 57 distributers had a window for adjusting points. Initial setting is .019 Dwell 30* I have a 57 283 all stock and the Distributer in it was 1110890
