Hello. I am new to this and have a few questions about my current project. I have a 1952 chevy 3600 216 I6 with 4 speed manual. I would like to keep the stock engine however it has a cracked block so I recently purchased a 250 I6 out of a early 1970's c-10. My questions were in regards to the transmission. Will my current transmission bolt up to my newer engine? I'm finding it hard to get an answer to my question. And also is it worth it to rebuild my current 4 speed manual or should I just buy one already rebuilt? I would like to keep it a manual. I'm not looking to make it a racer, just something to be able to drive on the highway and go to car shows in with the family. I appreciate any feed back. Thanks.
