Technical 283 identification

68 C 10 327 if it is YV. Y pretty well says it is a 66/68 truck 327.

 

I wouldn't know lol

 

I guess he doesn't want to sell it?

 

Interesting

 

I think most every small journal 327 I've had was a 657 block

 

the only one I've ever had was an 817.

 

Whats in the Vette?

 

Just an older guy. I should have made sure to get my own pictures when looking at it. I left and realized they weren't very clear

 

I would say by the shape of the flange of the crankshaft it's a 327.

 

Could what looks like a W be an M that was stamped upside down?

 

Dyslexic assembly guy at gm
Probably me in another life

 

I like the big trucks. Good cranks.
Some had oddball casting head numbers. Old round track guys around here used em.

 

I worked on one of the early 60s cabover trucks that had a 327 with a crank driven radiator fan. Had broken a crankshaft. I will never forget working at that shop, I have life enlightening experience from that place. Lucky to make it out not maimed or dead.

 

not many guys have the truck book

 

Unless its stupid money, its worth the asking price, those arent just laying around anymore. Good Luck.

 

Maybe
The Magnaflux test is going to verify that!

 

Thank you everyone!

 

The motor was cheap so I grabbed it. Don't really know much but starting to pull it apart to get more info. I cleaned and got some more pictures.

 

the stamp looks like...the engine was "decked", and then restamped with the original numbers, but not with the original style stamps. That's why the "W" looks so weird, it's an upside down M. But the original stamp is clearly visible.

The diagonal machining marks are the evidence that it was decked, originally it had been broached, the machine marks are lines that go from front to back.

That head is from 1965.

 

I noticed the faint stamp and I thought that may be the case. The numbers do appear to match up.

It's truly amazing the details you can remember, thank you!

 

What would cause someone to machine down the block "decking"?

 

If the deck surface is damaged by corrosion or something, or if they want to "square" the block to the crankshaft center line.

 

It’s a 4” bore block. In 67 the 327 that used this block were small journal, GM also used this same block for the 350 in the Camaro machined for the large journal 350 crank. I have the same block sitting in my coupe ( mines a 327 small journal)
