i recently found a set of 840 heads at a machine shop with E of 67 on them.were 840 heads used on any late production 67 cars? thanks greg

From Mortec....3919840....67-69...rect..CLOSED..396, 427, 107cc chamber

They were used clear into the late 69 model year. I have come across late 69 Camaros (they were built longer) that had 291s but never a Chevelle in 69 that didn't use them.

thanks for the info.does anybody know if 840 heads were used on 67 l78 chevelles? greg
