Don't get rid of the old 350 you may very well need it again ... any good running 350 is better than a broken 400

The engine I'm considering buying is a 76 400 with automatic attached to it. It may have originally been in an automatic or manual car.--no way of telling. My transmission is manual.
I wonder if it's a good idea to buy this engine without knowing what the crank looks like on the back?? According to post #40 in the thread below, mid 70's Pontiac cranks weren't drilled at all?? https://forums.maxperformanceinc.com...+pilot+bearing |

Well I got pictures of the crank and it looks good! Should accept a pilot bushing... or bearing.

Is the crank register the smaller one?
(looks like it could be)

I'm thinking it is because the block is a 557. It looks like the smaller one to me 2 1/2".

I went ahead and bought the 557 block 400! Everything seems good at this point. Startup is probably months away...Hopefully by spring. So much other preparation to do. Thanks to everyone who helped me evaluate what I was looking at!

For many years i had a Pontiac V8 engine core program going. On occasion I would pick up '76-78 500557 shortblocks, then simply shell them out for the good condition smaller register 400 cranks, as well as oilpans, timing covers, valley pans, & hardware. Two of the '77 500557's I stripped down, the stock cranks had the correct recess for a pilot bearing. Both of those cranks were needed in 4speed W72 TransAm engines where the owner had spun a rod bearing & was still wanting to run the stock small register 11" cast flywheel.

Also I do plan on removing the pan to replace the rear seal. I should be able to find the crank date then. I am considering installing a BOP 2-piece seal like link below... https://www.ebay.com/itm/225319050821 |

I see the big "75" cast by the Distributor hole, so I'm betting that date is A155, or Jan 15, 1975. Hard to tell for sure in the pic, maybe hard to tell in person as well. Try a wire brush over the casting date and see if it doesn't become more of a '5' at the end.
It seems unlikely to me to be cast with the big number 75 by the distributor and be a 76 engine, which A156 would be.

The best way to ID the year is by the partial VIN on the block.
The pic of the date code is hard to tell for sure if the last digit is a '5' or '6', but I think it is a '6' (1976) I have seen some blocks with the 2 digit cast year for the next year of production. (would have to check notes if any in 1976 though)

I just checked VIN code on the block. 8th digit from the end is also a 6.

1976 year before, 1973 no year, 1972 year after. No sure what the big numbers are supposed to mean. |

The large numbers are intended model year fitment the 4 digit codes are the actual day the molten metal was poured into the mold
