What are the mod's and parts I would have to change?
The 230 Block Casting number is 3788406.
I did a Casting Number search on the internet.
Why is it that some Blocks are listed as 230-250?
But this 3788406 is only listed as a 230 block?
And would 1970-1975 250 cid parts,Head fit on this 230 block?
I gess im wondering if a Block casting is only listed as 230 cid.
There must be a reason why it can't be made into a 250 cid?
