1970 L78 vs LS5 Valve Covers

[WILMASBOYL78]

I would lean towards the CKQ from a Chevelle by what is visible...

Only question is the breather hose...the 1970 models used a low profile intake manifold, and the hose was shaped to allow for the lowered air filter base.

The CKQ indicated a HD clutch with the L78 application...a rare item from my experience. Also, I have never seen the valve cover sticker on a BB Nova.

Also, pretty sure the Nova valve cover [drivers side] had a small indent for the booster.

Thanks - I think it's a K. And maybe the covers on the LS5 were the exact same part anyway? I found a pic of an L78 restoration which shows a short straight breather hose on a cowl car - whether that was correct or not.

That photo tells the story...the spacer on top of the carb raises the level of the air cleaner so that a straight hose is correct. There was no cowl hood on the Nova...your valve covers are a Chevelle item and definitely one with a cowl hood.

Covers for LS5-6 were the same as far as I know...

Tom, When are you going to send me photo's of your original Nova BB drivers side valve covers so I can verify them or you could post a photo here of the drivers side & the location of the top rear plug wire stand.
