Can anyone ID this engine?

[Joe Blaze]

I have a couple of questions on my new '71 Blazer maybe some Chevy lovers can help with.
Can anyone help ID the engine from the photos? The guy I got it from said he thought it was a rebuilt 350, but that's because that's what the guy before him said it was. He didn't know how to tell, and neither do I. There is a number stamped on the front of the block below the A/C compressor "V0426TBG". What does it mean?
Is the alternator on the correct side for a '71?
What should be connected to the valve cover nipple in photo #4?
Cab anyone tell by that distributor cover if I have points for the ignition?
Thanks

That there be the coil inside the top of the dizzy cap, so it's HEI (uhh, 1975+ electronic ignition, NOT points.) For which you should be very very thankful, 'cuz points suck. Since it's been converted, I recommend that you trace the power wire to it. Make sure it's heavy gauge and goes to the fusebox or a relay. The original points wire has a resistor in it hidden away, and while it will (sort of) fire the HEI, it'll only get like seven or eight volts to the coil instead of 12, and it'll run like crap. Been there, done that.

And I'm surprised the plastic fuel filter hasn't melted yet -- I advise a metal one, and hose clamps.

Can't speak to the ID of the motor; IIRC there are numbers on the block sides somewhere, but 4x4High or somebody clueful will post up.

Oh, and the nipple on the driver's side valve cover is a PCV valve; it was connected via vacuum hose to the front of the Q-Jet carb and/or the charcoal canister.

According to what I found it is a '71 350. http://www.73-87.com/chevy_ids/scode6.htm

The nipple is pcv valve

Head is most likely a 993 truck casting for a 350. V0426 is Flint Mi. April 26 build where/when. TBG is a1971 350 4bbl w/ 255 h/p in K-10 to 2500.
Edited to back up with the following:
Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code)
Another example: T0830CTY - (T = Tonawanda, 08 = August, 30 = 30th day, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400)

The nipple should be the PCV valve, hooked to manifold vacuum.

The engine ID number shown states it is V0426TBG

V- indicates the engine was built at the Flint Michigan Assembly Plant
04- indicates April was the build month
26- indicates the 26th day of the month
TBG- indicates the engine is a 1971 350 out of a C-10 - 2500, when built, it was combined with a A/T mating, and it produced 255 hp.

Without number looking I'm pretty sure only the early 350s (pre one piece rear main seal blocks) have the oil plug above the timing cover.

Almost all 010 blocks have that fitting.

Slapperbar, I agree with location, I fixed mine to state Flint Assembly Plant as I was looking at the V 1st digit for a 350 block with CNR instead of TBG, but everything else is correct and we are with the same info.

All I run are Fram G-3s. Unless they are sitting on the exhaust manifold/header, they will not melt. The good thing is you can see the fuel flow and if there is dirt/water in them.

Thanks to all for the helpful responses.

Alternator location is correct with the short water pump for the year

Ok, I was wrong, I checked a 68 327, 71 350, 89 350 and all had the plug, the only ones who.didn't was a 76 400 and a 98 350 out of my stash, so the plug doesn't matter I guess
