Any one have experience with repower from Straight 6 KL type motor to a 283 V8. Have 18' 1956 Continental (utility style). Pulled motor and sent to Engine shop for evaluation. I'm not holding out much hope it's economically realistic to repair. Crack in #4 cyl and milky oil. Previous owner Didn't winterize (Michigan).
Would like to repower with a Chris Craft (Chevy) 283 V8. Chris Craft started using the 283 in the 18 footer in '58 or' 59 I believe. Pictures show similar mount on stringers. I would like some dimensions; preferably engineering drawings. Any suggestions would be appreciated.

Re: KL to 283 repower
The 283 appeared in 59 I believe. The conversion should be fairly straightforward and has been done quite often. I would suggest considering a 350 with the 283 Chris Craft accessories and look as it will be more power (even if you don’t need it) and less money than a true 283 due to parts availability and demand.
Re: KL to 283 repower
You will need to pay attention to minimum exhaust pipe size for a 283 or 350 engine if you plan on using only 1 exhaust pipe. Most likely the old KL exhaust diameter will be too small to combine both exhausts into one. You may also want to go with 2 exhaust pipes instead. You definitely will want the manual (non hydraulic) transmission to better match up to the existing shift linkage, although some modifications might be needed to the length of the linkage pipe.
This is a link to a 283 manual with some installation information about exhaust sizes, different water intakes, etc.:

If you Google the CC 283, there are some engineered drawings with dimensions and transmission shaft location.
