How do I Identify if actual factual 400s/b ?
Have an 81 elky that is supposed to be a 400, installed by previous owner.
It will eventually be coming out, with a different motor going in.
It tossed a belt and overheated, don't know if good core or not.

The casting number off the back of the block behind the drivers side head. I think the last three numbers are 509, 817, or 511 to be a 400.

The 511 is the 4 bolt and it has 3 frost plugs on each side of the block where the o5hers have only 2 on each side.

Did more reading about these engine last night and a few people claim some 509's had the 4 bolt too.
After reading I remembered all the 400's I removed in the mid/late seventies for spun rod bearings and water jacket cracks...
I never did replace one with another 400, we always put a 350 in it's place.
Just go buy a Dart block and have something really different..

Looks like an 817
Talked to son, we are sure something can be arranged if you think this will work.
Overheated, doesn't want to stay running.

Karl is the car blowing white smoke that coolant is getting into the cylinders? I’m a little afraid if it was overheated that bad if the block might be damaged or cracked.

And check the dipstick for white/grey sludge or overfull...

Usually an overheated block is OK, but almost always can be saved by decking it a little, which is a good idea anyway. It can inexpensively be checked for cracks.

I will check with my Brother-in-law on the details, but he just said a buddy of his offered him 2 400sbc engines.

I know where there is a 400 but he wants $100 for it.
