I don't believe so. 1 thing is certain, you cannot make a 4-bolt small journal block. There is not enough meat in a GM SJ block to make it happen. Therefore '67 back is out(except for '67 350 Camaro or Z28 which is large journal). So it would have to be a '68 up large journal block. There are no LJ 4-bolt blocks in '68 model year. So it could only be a '69 or '70. By that time the 350 was out and everybody was gravitating to it-from what I am seeing including Chris Craft. I have never seen any evidence of a factory 327 4-bolt in any application-marine, combine, over the counter, etc. People built them, but GM never did. All of these engines for outside are still built by GM engine plants so they can't have components that didn't exist at that time. They were just marineized or agriculturized by other companies like Mercury Marine or Pleasurecraft Marine for boats or Massey Ferguson or whoever with special exhaust manifolds or accessories.
