There is major engine knocking coming from my '51 Chevy 3600 (216 engine). friends think a connecting rod issue. I'd like to repair (if affordable), but can't do this type of work, so if my mechanic is willing should I go ahead, or look to replace the whole engine? Any idea the number of mechanic hours required? And as long as he's in tehre shouold I do other repairs or have him look for other potential issues? I'm looking for any advice from those who have gone through the process. Thank you.
