Inline 6 Identification - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mismith · 12-20-2021, 11:55 PM

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?

Thanks for your help!

589180 is the unique vehicle serial number (to match against vehicle VIN).

The Oracle of Google returns many hits. Can't remember which one now.
