'66 C10 engine swap....step in plz.

im pulling the 250 lb6 out of my c10. id like to put a 292 lb6 back into it. my question is...will the tranny bolt right up to the 292? i would think that the 250 and 292 share the same block...just the 292 has a larger bore. am i right? and also as a last thought...are the fly wheels the same size also? thanx to any that respond!

The bolt pattern is the same on all chevy v-8.Fly wheel not sure.

this is a st8 six. but i believe it would bolt up to my tranny.

do you have any information on which transmissions i can put in my 66 c 10 292 pick up without altering the driveshaft?
