64 365hp timing chain cover question?

[Jaime M.]

Hi Everyone,
Did GM use two different timing chain covers for the 8" balancer?

Jaime -

The one in the left side photo (with the "pie slices" indentation) appears to be an OEM part, but the one in the right side photo (flat indentation) is not (at least not from the midyear era).

Thanks John
The covers are both repo listed by two different corvette parts suppliers. You would think that a corvette parts supplier that just specializes in C2's would sell a correct part if they are listing it as being so. Anyone have an original for sale?

The cover on the right is the correct, original style.

The cover on the left is a much later cover, from about the mid 70's or even later. It will SERVICE any small block application but it's not correct for earlier engines.

Original style covers with a timing tab for an 8" balancer are hard to find. However, covers of the original configuration with a timing tab for smaller balancers are quite common and easy to come by. The tab can be carefully removed from these and a reproduction tab for an 8" balancer welded-on. Beware, though, many original covers suffer from distortion damage (usually caused by klutz efforts to install a new seal) or damage from loose timing chains.

So the one the right without the pie like slices is correct for the 64 365hp motor with an 8" balancer?

Jaime,

As Joe mentioned, the cover on the right would be correct for your 64, unless you happen to have an early 64. (before aprox VIN #5000?)

The correct cover for a 64 built before aprox VIN #5000 would have a timing tab with a different method of attachment that is obvious even after the engine is assembled.

My car has VIN # 112305. I know about the early tab configuration but I was not certain if it had the pie like slice or not. Someone has posted this cover on ebay as OEM being correct 62 to 65 corvette with 8" balancer.

The one pictured is a correct cover.

Joe, now I'm confused. I'm thinkin' you must've flipped the description by mistake, especially since the above comment seems to contradict your #9 post after the E Bay picture. All my smallblock stuff has been '59 through '60's, but I've never even seen the one on the right.

The "tri-spoke" style cover (shown on the right in the original post in this thread) is the only style that I have ever seen on original small blocks through the mid 70's.

Joe, now I'm really confused. (two confused ikons on that 'un) I've dun' had the ole' gal come down and look at both my feet and tell me which one is right and which one is left and based on what she's tellin' me and what I thunk' already that picture on the top corner which has the 3 spokes would be considered left. Now I fully understand that if'n you're sittin in a car that the driver's seat is left and the passenger is right. (since the ole' gal sits in the right seat and is always right that one is easy to remember) What I ain't followin' is how the picture in the top left corner up there is right and the one closer to the middle is left. Either my computer is flippin' pictures, I'm dislexic, or I need to go back to school and learn my left from my right. Don't we read from left to right and write from left to write?

Tom, you're right, meaning correct NOT the opposite of left. I was never in the army, but I did end up with a pair of female ROTC cadets in my room in college overnight one time and now I'm wonderin' if the blonde was on my right or my left. That could be awful embarrassin' at a reunion if I got 'em mixed up.

One other thing I never could master was that wind direction thing when I was in flight school. Seems like if you've got a North wind the wind would be blowin' North. When you say you're takin' a trip South you ain't headin' up North, so why does the daggum wind work in opposite directions? If I've got a South wind on my tail it oughta mean I'm headed for Florida, NOT New York.

Norris,

On my computer, the correct cover is on the right in your pictures. I suppose if you're on the other side of the equator, or perhaps on the other side of your monitor, the correct one may be on the left though. Also possible that your computer is plugged in backwards.

Actually, I think John Hinckley meant the one on the right too.

Michael -

Maybe different browsers display the photos in a different order - that's why I added the description of each one ("pie-slices" vs. "flat" indentations) to my original response. The one with the pie-slices is correct, and the flat one is not.
