I don't know if this is the right place to ask this question but thought it was a good place to start. I've got a tri 5 Chevy that has what I was told was a mid 80's 350. I have starter problems and was asked to identify which motor it was. The flat surface on the block in front of the right cylinder did not have any numbers stamped so I went to the back of the block and the casting number was 3970010 which I referenced as a 1969 Z28 302. It does not have double hump heads and I'm pretty sure it does not have solids. I really question that this is a 302 motor. Any other way of identifying what motor this is?

I may have answered my own question....I just found a website that says the 3970010 casting was also used for 1969-1980 350 motors. That's probably what I've got.

According to this:

That casting could be a 302, 327, or 350.

1carguy,

I have that same casting number block in my '32 Ford roadster street rod. As Pete says it was used in a variety of displacements and there were 2 and 4 bolt versions of it. A pretty versatile casting, huh?

When I was looking for a core to build into a street rod engine I found mine at, of all places, a Chevy dealer service department. It is a 1978 350 cid 4-bolt truck engine.

Thanks for the input guys. I also looked for a stamped number on top of the block in front of the right cylinder head and there is nothing there, so it's going to be tough to identify this motor. Not knowing what it is makes it a little tougher buying parts for it as I experienced last week buying a starter. You'd think all the sb starters would be the same but not true.

Yea, computers have actually made it harder to get parts if you do an engine or tranny swap these days. When I put a NV3500 in my truck, the GM parts counter couldn't give me a part number for the transmission fluid without a VIN number. It used to be when you went to a parts counter and asked for a SBC starter, the person behind the counter would have asked a few questions, like whether it bolted to the bellhousing or engine and then walk back and hand you what you need. These days, their computer system requires them to enter year, make, model, transmission and trim level to give a part number. Today, those motors are all 20+ years old, and I guess they just don't sell that many parts for them anymore. Also the staff are reliant on their computer systems, which don't give a year range for a part, they just give one part number for one application. In reality, there aren't a lot of different starters for a small block chevy, but it's not as easy as it once was for the parts store employees to know the differences.

Off topic....

Back in the 1980's, I used to work at auto parts stores during summer break while going to college.

This old, grumpy guy (not Grumpy Vette) comes in and asks for a water pump for a Chevy. He refused to give me year, model or engine. He got really irritated and yelled at me, "It don't matter. They're all the same."

I purposely gave him a water pump I knew wouldn't fit...one for a 235 six.

Yeah, he came back about 30 minutes later with the information I asked for.

1carguy,

How hard would it be to open a few boxes looking for a starter with either the "straight" or "angled" bolt holes you need?

I've found parts store personnel to be very helpful in finding parts for odd applications, like radiator hoses with complicated curves and different size ends needed for engine swaps.

Does your old starter have any identification information on it? If not, as long as you know whether you have a straight or angled bolt starter, you could order one from Summit that will work with either flex plate.

I did the same thing to a guy once. Came in being very arrogant. Wanted a water pump for a 427 Chevy. Wouldn't tell me the year or model. I sent him trucking with the short small block water pump used on a C60 truck tall deck 427. Needless to say he came in and asked for the manager on duty which was me. He said I asked for a big block 427 pump not a small block pump. I explained to him the small block pump is the pump for a 427 in a truck application. You never would tell me what you where working on so I assumed it was a big truck. Never had an issue with that guy providing information after that.

No such thing as a "302 block" - it's the same block used for many other applications; the only thing that makes it a "302" is the crank, rods, pistons, cam, and heads assembled to it, and the suffix code stamped on the pad later - there's nothing "special" about the block.

Take your starter to the parts store and ask for another one like it.
