3970010 block is a four inch bole large main bearing unit produced from late 68 into the late seventies. It is one of the most common of these blocks. It was used as 302-327-350 base. As for the trans what is the shape of the pan? square (powerglide) or square with one corner cut short (350 turbo).
The tranny is square with like a 45 degree angle cut on the one corner.

So the block is a 350? If so, then what is the VO8OTKT mean?

Thanks for all the help!
