426 Hemi timing chain covers and water pump housing?

[hemi68charger]

Hey again,,
Heard on my previous thread on the hemi distributor holddown that the timing chain cover and water pump housing are different on a 426 hemi than a 440 hp. Anyone have thoughts and/pics of this? I test fitted my original hemi dampner and timing chain cover I have and the gap between the dampner and timing scale look not much different, if any, compared to my 69 440 hp in my C500....

The chain cover is the same for Hemi and all big blocks.
On a year-for-year basis, the water pump housing is he same for the Hemi and any other non-A/C big block.

I agree with John. 

I found a thread a few months back on the Moparts.com A12 forum where they were talking about water pump housings.  There were a couple of links to some old newsletter articles about Hemi water pump housings, etc.  They mention where the engine plant had to grind a little on the underneath side of the WP housing.  Most of the really good info is in the attachments posted to that thread.

This'll probably do the trick for you, Troy.
