What 6 cylinder is in my latest project ‘66? I’ve searched quite a bit and cannot find this block casting number in anyone’s list. The identification code leads me to believe it’s a 1971 year but there’s a lot I cannot find on it as well.
Block casting # 399425
Engine ID Code- F0604CAB Engine VIN- 11N589180
What vehicle was Suffix Code “CAB”? Is this a 250 or a 292?
230 and 250 engines use the same block. The cubic inch difference is in the crankshaft stroke. 292 engines have a taller side cover, and the motor mounts are offset about 3" from side to side. If you can get a borescope into a cylinder through a spark plug hole, look at the top of a piston. 230 engines have flat top pistons. 250's have dish tops. In the mid-1960's there was also a 194 cubic inch six used in the sub-compact Chevy II that looks similar to a 230/250. Jerry
