Not at all. The post is about engine identification and "what the engine is out of". And given the fact that the Varajet didn't make the scene until '79 then Ric has a '73 short block with a later head.

And I see a typo up above - I meant '79 not '75. I read somewhere that the 2 barrel integrated with a varajet was created with the RPO LE3 truck application in mind - even though the varajet was used elsewhere.

I was under the impression that all 250's after '75 were integrated heads (cause of smog requirements) - and that all 79-84 trucks with a 250 were LE3 equipped.
