Vintage day 2 Valve Covers - M/T & Edelbrock

Can anyone date these valve covers? I purchased these two sets. The first is a set of Edelbrock curved script cast aluminum covers with knockouts for the PCV and the oil fill. The other set is M/T tall cast aluminum valve covers for a BBC without the 427 cast in the PCV knockout area. The underside of the M/T valve covers say 396-427, Made in Japan and have part number 3278396. Also what vintage are the Offy breathers?

I wet sanded and polished both sets by hand. The Edelbrock's found their way onto my 1972 El Camino, the Mickey Thompson's will find their way onto my 402cu big block in my '59 Apache!

Thanks guys

I can only tell you this: I bought my M/T big block covers new in '69 and they had "427" cast into the round circle next to the center. That always bothered me 'cause my engine was a 396 L-78 at the time. I didn't want anyone thinking I had a bigger motor than I did. It hurt the odds.

Verne, thanks for the AWESOME picture!!! Those valve covers look great on that car. I have seen these M/T valve covers many times with the 427, but I've only seen a handful of sets of these without the 427, that has me intrigued.

The covers you have came out in the early 70's and the ones marked made in Japan were later 70's to early 80's... I have seen more non 427 M/T covers then real 427 covers... Mark
