And if you really want to get technical it was a 200hp 2bbl

Here is another one. VO627 CKZ. Regarding the heads, which are better the 882s or 441s. I assume the 441s as they are slightly larger in volume.

block..........3970010
block casting date....F264
Heads....333882
heads casting date....N264
pad near alternator.......VO627 CKZ

CKZ 1974 350 4 spd trans. J L48 195 4 Vette

Several answers come up for that code all are Corvette engines
V=Flint
06= June
27= 27th day of the month
CKZ=
1972 LT-1, HD 4 speed 255HP
1973 L48, 4 speed 190HP
1974 L48 4speed 195 HP
1977 L48, 4 speed 180 HP

you're gonna hafta check the block casting date/part number to say which year it is for sure--FED387

Hey FED what is this code. vo426xcd any idea?

FED 387 · 02-03-2012, 01:36 PM

probably an over the counter replacement engine/block or a left over engine that was put into a "next year" vehicle say a 1969 into a 1970 --since the engine code for 1970 would not be correct on a 1969 engine they used a X to denote the change---most likely an LT-1 but you'll hafta check the heads/intake to be sure
