couple stupid questions on a TH350 and a 350

[stackz]

ok, I picked up this 350 and TH350 the other day thats been at my parents house since about 2002-ish. dad just remembers that it came out of a 63 truck and ran/drove. engine spins so I bought them from him about 10 years ago for $300. dad always said the guy told him it was a 327.

meh. I dont care either way but turns out its a 350. block number is 3970014 and the date code looks to be A10 73 (so maybe January 10, 1973?). it is stamped up front 14N129383 and T1112CMA.



so from here: https://www.nastyz28.com/chevy-engin...-stampings.php

it looks to break the partial vin to (1=chevy), (4=1974), (N=Norwood assembly plant), and 129383 is the build number.

question 1 - is there any way to look up the ranges of which body was being assembled as opposed to the others for my number?

I ask this question as the reference website, under the second picture reference, they mention "4xxx is the corvette range" so it seems GM would just pump out a bunch of the same car in the same vin range so I guess this info is somewhere out there?

for the engine ID code, it matches the other one so T= Tonawanda engine plant, 11=November, 12=12th day, CMA= is either 72 or 74 and it is a 1974 so 350 turbo hydramatic, 2 barrel, A B F or X body code. so yeah, block was cast in 73 and then engine put together in 74. heads look to be original to the original build as they are 333882 with date code K 8 73. so November 8, 1973 is when they were cast...kinda like the block.

what throws me off is the intake and carb...and I think maybe why the guy my dad got it from thought it was a 327... intake is 3919803 which breaks to a 1969 327 or 350 camaro intake manifold and the carb was a quadrajet number 7029223 which breaks to a 1969 350 truck carb of all things haha.

but yeah, I believe what I have is a generic 350 from 1974 from a car originally equipped with a 2 barrel intake/carb and this other stuff was swapped on at some point.

question 2 - does anyone know if all of the 1974 A/B/F/X body cars shared the same stock 2 barrel engine so then I'll know more about the stock compression ratio and cam specs? I dont even know what these "bodies" were...

I'm thinking it may have a cam in it as well as it had headers on it but wont know that until later on.

It came with a TH350 but I have never laid eyes on one before (I usually mess with fords).

question 3 - does this look like a stock torque converter or an aftermarket stall converter?

It looks tiny and like its had tabs welded to it.

question 4 - like fords, am I missing a flexplate that goes between the motor and transmission? I couldnt find one anywhere near the stuff in storage but honestly not sure as this will be the first small block chevy I'm messing around with.

thanks for any help with this stuff is greatly appreciated. I'd just like to be able to nail down what exactly the engine came out of is all. I could care less honestly but it would be neat to be able to say "its a 350 out of a 74 monte carlo...or whatever" just for giggles. And no, considering this was a 2 barrel equipped car originally, I do NOT expect it to be a 4 bolt main, nor do I care, I just want a good running motor hah.
