Small Block Chevrolet numbers


JimD

Recommended Posts

I'll ask here because of the wealth of knowledge and experience.

We have a non-running SBC and would like to know the original displacement. Two numbers are available; on the left rear, 460776 is cast into the block.

On the right front near the water pump mounting these numbers are stamped into the block; TO707CEJ, 180334888.

Help or guidance is appreciated.

460776.....305 cu in, ...1978-1979... 2 Main Cap bolts

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

When I saw this topic, I started to think about how many different displacements that these SBC engines were sold from the factory in cars or trucks.

No after market like 383 or such.

I came up with the following:

265, 283, 327, 350, 302, 307, 400, 262 (Chevy Monza)

To go from 262 to 400 using the same basic block & head design is a tribute to the sliderule crowd that designed it!

GM does market a 383 SBC as a crate engine.

Is this a complete SBC displacement list, or did I miss any?

I think Oldsmobile had perhaps the largest spread of engine displacements using the same basic small block design. 260, 307, 350, 403. I've had two 307s before, and a 403 punched out to 408 (.030 over). Those cylinder walls were paper-dadgum-thin on that 403 after the cylinder cleanup. Comparatively, a 260 and 307 engine has a LOT of meat in the block...same bore spacing but much smaller bores.

Looks like I missed the following:

14016376...267...79-82...2 :o

A 267 C.I. from 1979 to 1982? News to me! I'm surprised that I missed that one!

I am familiar with the 4.3 liter V-6, but a 4.3 liter V-8? I still missed it. What & where was it used in? 1979 to 1982? I am still drawing a blank! :o

I think my friend had this V8 engine in a Caprice, I had a hard time stopping an off closed throttle bog (felt like an accelerator pump problem)...

I had one of those "special" 267's in my Buick regal back in the day, the only good thing about it was that I was able to re-use the stock motor mounts when I put in the 406 stoker motor I built for it! What a difference, from about 16.80 in the 1/4 mile to eventually 12.80's with street slicks!

Wow -- d'you have nitrous on that 267? I wouldn't think a stock smogger 267 would be able to break into the TEENS in the 1/4!
