Head is ok. I can get a Inline 6 230 engine casting number 3788406. And since the only casting listing I could find on the internet said its a 230 block. Im not sure if I can make this Block 3788406 into a 250 cid engine. So can ALL 230cid blocks be made into a 250cid? And since a 230 has a shorter stroke would a 230 cid run at a higher RPM,than a 250 cid? | | |
