Re: More Chevelle updates

If memory serves me the 291 and 840 heads are semi interchangeable [except maybe for the spark plugs..one was a small plug if I remember..] I think they CC'ed within 1 0r 2 CCs...

Are you thinking maybe you'll need a bigger, better intake manifold with the ported heads?

Any reason you went closed chamber in the original build?
