Another engine code question: wtf does "PKC" code for?
Looking at a NOM, otherwise sweet '69 "L46" car for sale.
Have checked the usual sources of engine code info' (Lime Book, NastyZ28, etc.) and can't find any reference to this legit-looking "PKC" engine code suffix (see attached).
Anybody have a clue what a PKC code might indicate?
If it helps, there are also "5.7LG" and "SGI" cast (not stamped) on the block in one area and what looks to be "140_____" in another area, but it's hard to read the top half of the digits. Looks like it is likely "14093638" which suggest some 350 ci motor cast from 1986 to 1994.
My questions are, what does "PKC" code for and is this an ok replacement block for a '69 L46 (4 bolt main etc.) or a boat anchor?
Thanks!!!

i see nothing for RKC, PKC or BKC but if it is 86 to 94 350 it is a onepiece rear seal probably roller and probably no manual fuel pump engine. if it has a manual pump on it, it may well be a marine or other over the counter engine. there is no vin derivative below the RPO code. this one is in the US. looks like a pretty clean car with honest seller with lots of pics and history. might be worth the trip and ship... https://www.corvetteforum.com/forums...my-1972-a.html

I check marine block this was not used in that application. If I was to do a "SWAG" (Scientific Wild *** Guess)., As the PKA and PKD were used in trucks in 1988 would say the PKC was used in a truck in 1988. Also look above the oil filter on the block as the VIN were getting very long at this point. That was the alternate location for VIN stamp. Also have read that sometimes the VIN was stamped in one of the heads.

I checked out the advert you sent - thanks for that, too. Sadly, the ads that provide the most pix, also reveal the most issues. Life ain't fair. This black coupe's birdcage showed some so-so rust. What the pix show didn't scare me directly, but it makes you wonder what lies deeper. I'm going to go back and look at that again.

I like your swag. Wait a minute, that sounds weird...
Anyway, I don't doubt it. In my many searches for a car to buy, I've come across several other C3s that had boring SBCs dropped in them. Sacrilege!!
But I can only go by the pix provided as I'm nowhere near the car (like, on another continent...).
Thanks for your help,
Steve, in the NLs

so it is a 95 350. last year pre-vortec. definitely a roller cam and no fuel pump mount. these heads i think had the 2 center bolts at a different angle than the 4 end bolts. sand were not well regarded as a performance head. but as with most engines retrofitted into a corvette it was probably not left in it's pickup truck configuration. so i would research what heads and intake are on it, but not rule out the car because of this engine.

Pardon my ignorance, but I don't know what you mean about, " the 2 center bolts at a different angle than the 4 end bolts". The seller says he THINKS the heads are original to the car, for what that's worth... It WAS originally an L46 (350/350) car. So, from what you're saying, having the original heads would be quite a plus.
Ok, you wanna REALLY impress me??? Tell me if the casting signs/shapes behind the stamp pad indicate what kind of heads they are. Even I can tell that they're not the coveted "camel humps":

what valve covers does it have. everything 86-newer has 4 bolts in a row down the center of the valve covers. all C3 era corvettes had 4 bolts on the perimeter of the valve cover. 2 on top (intake side) and 2 on bottom (exhaust side). if he is claiming probably correct orig heads, they are perimeter bolt ones. do you have a whole engine pic?

Valve covers are the super-cool finned ones of the C3 era. Engine bay is sweet, no?
