Does Mopar Use Refurb 426s for Crates?

Postby scottm » Fri Nov 19, 2004 7:17 pm

A website visitor from Holland emailed me an interesting question.
He has a "crate 426 Hemi" that came with a 5249667 part number.
But the motor also has the 2468330 casting number on the block.
Which is the casting number on the 1964-1971 426 Hemi engines.

Does/did Mopar re-use old blocks for their 426 crate Hemi motors?
Maybe this casting is also used on their newly created blocks, too?

They used the same casting number on the new blocks but it is followed by M. This is how they designate the new and the old blocks.
