Technical Chevy Small Block Identification

I am trying to ID my small block Chevy engine and I come up with it being a 1972 350 Truck engine. This is not at all what I thought it was but the numbers shouldn't lie?
Here are the numbers:
3970010
10 01
K11 19 TDG
Please let me know if I am looking at this correctly.
thanks,
Joe

 

The suffix starts with T, it's three letters, and the block is an 010, so yeah, it's a 70s truck motor.

 

Thanks Squirrel!

 

010 just means 4 inch bore, almost every carbed 350 had that casting number and probably small journal 327s too I suppose.

 

I thought the last three numbers 010, indicated a 4 bolt main block?

 

010 is the last three digits of the casting number, most of the 010 blocks are 4 bolt, some are 2 bolt. They were used mostly in trucks, and corvettes and high perf camaros, from 69-79. Most of the 2 bolt blocks from the 70s were the 014 casting, which is very similar to the 010.

 

How true is it that if these 350 blocks have that little plug, just below the front of intake, mean a 4 bolt? The few of these I've had were 4 bolt - thanks!

 

I had a 283 with that plug.

Really, I think the plug or no plug thing is something about which engine plant it was made in. But I'm just guessing.

 

all SBCs are from vettes

 

All the 010 blocks I have ever had were 2 bolt mains. 327s are different casting numbers. I have seen plenty of 4 bolt 010 blocks, just never owned one.

 

and early ford hot rods

 

The ONLY thing that 010 means is that the casting is designed to be finished at a 4" bore.

Not high-nickel, not 4-bolt-main, not anything else.

The number of bolts that hold the main bearing caps on is a finishing machining process.

You can take a 2-bolt-main block and make it a 4-bolt-main block, with a mill, or sturdy large drill press.

 

the 350 in my bus was removed from a vette
was born in a 1 ton truck
010 4 bolt block

 

010 is a common truck block. Good as any. The 4 bolt main thing is overblown. I get it, if you are going to spend a lot of money building a 'sbc you should start with a 4 bolt lower end. Any one ever spun a main bearing in a SBC?

 

Yes. Twice.

 

2 or 4 bolt and cause? .................heading out to the shed to see what my 010 4 bolt is

 

Both 4-bolt. One unintentional down shift under a lot of boost. Pretty sure, by math it hit 9500rpm before it exploded.

That one broke the block, right through the outboard bolt hole in the webbing.

The other was a locked up oil pump.

Clean your oil p***ages better than I did.

I am really good at breaking things.

I don't even test drive customer cars anymore.

 

you can break anything if you try............ engine number starts V ends looks like TBX? ?

 

I am a well known rod thrower.

I limit myself to 400 hp these days.

 

better to be known as a thrower than a puller

 

Yes the two bolt main and 4 bolt main are the exact same block. Its simply that one is machined and drilled for four bolt main caps. A 4 bolt main don't make a bit more HP. Machine the 2 bolt maincaps flat and add a steel bar and studs and its stronger than a two bolt main.

 

No I haven't. its the rod bearings or pistons that have went south on every small block I ever tore up.

 

With some go fast parts will make an excellent hotrod or race engine...

The heart of my dragster is a 010 block

 

the extra bolts on my 350 provide zero HP
just something else to say when someone asks what it is

 

Little plug in front is for the trucks with compressors for the pressured lube. I think it came on all Flint blocks, car or truck?

 

The plug on the front of the block was on the first 265. It is for pressurized oil to flow to the oil filter that is mounted on the thermostat neck. The 55 eng did not have a oil filter like the 57 and up with the canister and later with the spin on filter. The return was on the p***enger side of the intake manifold.

 

If you're going to worry about running a 2 bolt block, you might think about worrying about using a standard 4 bolt block instead of a splayed cap setup. Just something else to keep you awake at night.

 

Between Squirrel and Gimpy we have it made.
