>Hello everyone,
I have a very interesting question for you classic enthusiast...

Whats the difference between a 1967 and 1969 Camaro Z/28 engine?
are they both DZ designated blocks and were they both 4 bolt mains or just the 1969 version?

I have a wager going on at work with another Camaro fanatic and I think that:
1969 was the 4 bolt and had the DZ designation only.

Thanks for your help

 

>oh and if you can post a link to the correct info that would be helpfull too... I can't use "because they said so" as proof.

 

In '67 the 302 had 2 bolt mains. In '68 it could have 2 or 4 bolt. In late '68 they started using the DZ designation and the block had 4 bolt mains. In '69 they had 4 bolt mains and the DZ designation on the engine pad.
