Engine ID

I'm interested too. My 1975 SN has the same set-up, except that the valve cover sticker says GT255. Otherwise same paint color, same mounts, etc.

The exhaust manifolds are the same too. The sticker on mine still reads, "correct craft" -- yours probably did too. Anyone know what those manifolds are and where someone can find a replacement end-riser?

The core of mine is a 351W 4 barrel-- yours may be a 302 block or a 2-barrel (GT255 v. GT220 ??). Looking forward to learning.   

The exhaust manifold (logs) had a sticker that used to read "Pleasure Craft Marine" what I can tell from some items in the reference section is it is the high output version of the 302 b/c it has the 4 barrel carburetor - I am assuming the GT220 sticker was an indication of HP rating since this coincides with items in the reference section as well - sooner or later I will be in for a rebuild and was just curious if there was any websites out there that could decipher the original factory setup. I have read that some of the "high output" 302's had larger valves which was essentially achieved by running 351 heads (don't really know for sure) but would be interesting to know - curiosity kills the cat sometimes and it is just fun learning about these old boats when it seems the OEM didn't keep much of a record

THANKS
