Timing chain cover
I am looking for a source for a timing chain cover for my 63 327 cu in 340 HP car. Any information appreciated.

Reproductions of this cover, including the welded-on timing tab, are available. Most of the vendors should carry them.
If you want an original, you'll have to scour the swap meets or eBay. The basic cover is easy to find. What's much tougher is to find one with a tab for an 8" balancer.
NOS is virtually out of the question. The exact cover used in PRODUCTION was discontinued so long ago I highly doubt you'd ever find one.In Appreciation of John Hinckley -
Re: Timing chain cover
Thanks Joe for the response. My original was recently damaged by accident. I guess I will go the repro route.

Re: Timing chain cover
Hi Richard, I've tried going the repro route but the tabs are all incorrect in both size of the base of the tab and direction that the bases are folded in. I ended up buying a 6" cover with the correct tab and, with a dremel, removing the tab and spot welding it into the correct 8" spot. I did 2 covers like this and both came out looking pretty good. If needed, I can attach a photo of the end result. Aloha...Comment

Re: Timing chain cover
Hi Joe,
Responses to previous threads on this subject all indicated that it really didn't matter, as the tabs used on the 6" and then also used for the 8" balancers would not indicate correct markings for the 8" balancer due to moving outward 1". When I moved the tab outwards, I kept the tab alignment exact with regards to the degree and backed off precisely 1". It looks just like the pictures I had of original timing covers. I'll need to find the thread that stated this because it has the information on the correct timing settings to use...Comment

Assuming that the same tabs were used for 6" and 8" balancers (they might have been for awhile but I don't think this was generally the case), that would only mean that the advance and retard degree marks would have been off. However, the TDC mark is the most important mark and, assuming the tab is attached at the precise location, would be accurate for both 6" and 8" balancers.In Appreciation of John HinckleyComment

Re: Timing chain cover
Joe...Here is the link to one of the threads indicating that the indexing marks are not properly spaced for 6" to 8" and was not fixed until sometime in the '64 model. I'll definitely heed your warnings. Once I start engine assembly, I'll need to make sure that I'm at TDC and see how I line up with the timing tab. I searched for quite a long time for an original cover with no luck, hence the 'manufactured' cover.

Yes, that's what I was trying to say in my parenthetical comment in my response #7, above. In other words, the tabs may have been the same for about 1962-63, but not thereafter. So, there were plenty of timing covers manufactured in the 62-67 period in which the tabs were NOT the same for engines with 6" and 8" balancers. Of course, as I mentioned and as you found, finding one of the covers for a 8" balancer is tough whether it's a 62-63 cover or a 64-67 cover.In Appreciation of John HinckleyComment
