Trying to find what I got...these help?

Trying to find out what kind of block I have in my 76 as the previous owner put a crate engine in there about 10 years ago from Jegs.

Where are those casting numbers located? They don't correspond to anything I know of.

And from the headers, that's a small block for sure.

It was from behind the alternator. For the life of me I can't see the one that is supposed to be on the back toward the tranny.

driver side of block on bell housing area just under the head surface is the BLOCK casting # . this gets you started . as some engines share blocks or cranks to get the end cid of the motor .

if a crate motor almost a good luck unless paper work or tear down to see whats inside it.

if its a good runner then you have a runswell motor .

It is probably a 290 horse 350, but could be a 200 horse stock replacement. The only way to tell is tear it down.

I have a simular motor. The Vin pad is much smaller than the factory motors.
I'm told the U.S. imported alot of 350 motors assembled in mexico.
This may or may not be your case.

A lot of the old "Targetmaster" and "Mr.Goodwrench" complete engines were not USA made,most of the ones made in Mexico had "Hencho En Mexico" casted in the side of the block towards the bell housing down near the freeze plug..
