Hi Paul,
I did end up going another route on the engine block. I bought the 827" Hemi parts motor off the classifieds a couple weeks ago.

Regarding your cover; I'm interested in a cover with cam drive, but I have a Jesel belt drive. Would your cover work with the Jesel? Or can it be modified to work?

Thanks, Gordon

Jesel belt drives and HFD Quick Change Timing Covers do not have any interchangable parts as manufactured, and the belt drive depends on its front cover casting for support. In this particular case, I think that modifications would be extensive. If you are asking because you wish to cover up your belt then I would recommend fabricating a cover for the belt drive setup that you already have.


I finally got home and picked this up. Very satisfied.
Thanks, Alan
Excellent, thanks very much, Alan, happy to hear. :)

We now have a new, optional cover plate for our Quick Change Timing Covers. You may opt for this new cover blank which is thinner than the standard Cover Plate and isn't machined for use with a cam-driven fuel pump. This narrower cover blank provides greater clearance for the mounting of an electric waterpump directly to our cover. Also works great for jet boats or other engine applications which do not use a cam-driven accessory.
