Parting a 68 right now that has a 327 listed on the spid in the glove box. The block casting numbers are 3914678. That could be a 302, 327, or 350 from 68-79. the intake is 3927184 which comes up as a 68 350 car only. The block pad numbers are VO705YV
Can i get some ideas from that? I thought all trucks had a "T" in the sequence. Everything appears original on it yet right down to the TH400 kickdown on the carb. Thanks for any help, Eric

Scroll down.

A search for Chevrolet smallblock suffix codes brings up more info than a sane person wants to deal with.

Thats what i got to. 68 327

**too much stuff** · 02-09-2010, 11:44 PM

The truck is a 68 and 327 is on the spid. However, the truck has an auto trans with the kickdown on the carb for a th400. I can't tell the engine has been replaced, but who knows. The trans was replaced from a 400 to a 350. So is this a truck or car engine. Also what is up with the bypass from the water pump to the intake? Thanks

It looks like the engine could be original, YV translates to 68 327 with manual transmission in a C-10, 220 hp with a 4 bbl carb. someone hooked a hose into the temperature sending location on the intake manifold. Not sure why as I don't see any reason for doing it. Also, the heater hoses look a little different!

mine is a 68 327 and has (had) the smae bypass hose... V0405YX (240HP)

**too much stuff** · 02-10-2010, 06:10 PM

So would we think the engine was replaced since it has an auto trans? I don't see any clue that it ever had a clutch. It still has the original plastic clutch delete even.
JimK, that is an old style hose heater and actually runs under the engine also. I have to look that mess over better...
So any ideas on the bypass hose???
Thanks for the info so far, Eric

JimKshortstep4x4 · 02-12-2010, 09:05 PM

I looked up the suffix code "YV" on GMC Pauls listings and it says that the engine is a 240 hp, with 4 bbl and had an automatic 3 speed transmission in it. Since your truck has an automatic and it has no signs of ever being a stick, (including the very rare plastic clutch hole block off plug), I have to believe that it is the original engine and transmission. If you will get the numbers off of the transmission, I can probably come up with information on it. (There is an aluminum tag on the side of the transmission that will have stamped codes on it. I believe the tag is on the right as I remember.

Jimk, that makes more sense for what you found. Unfortunately, i know the trans has been replaced with a turbo 350. I appreciate the help. Eric

Eric are you selling the motor?

I guess i would for the right price. Was told it ran fine. I cranked it over until it had good oil pressure before i started parting it. The gas was bad so i didn't try to get it running.

The manifold number is the same on my 69 3/4 ton which I am looking for a new manifold for which led me here.
