So nothing going on today it’s to damb cold and my back is half out so I’m muddling through FE stuff and was looking at Jays adapters and got down to the edelbrock 2991 Yates intake and that thing looks like a great manifold. A couple of inches higher than the torker2 and way shorter than like a tunnel ram setup ( only single carb). And a straight shot to the heads. Was this intake in the great intake comparison very curious if somebody is using one of these.

I wasn't making my intake adapters when I did the dyno testing for the book, so its not in there. But I have heard from several folks who run them that they really work well, although the Edelbrock 2863 manifold with the Dominator flange is even better. Note that the 2991 intake has to be machined to fit my intake adapter, and you have to have the Yates style adapter (part number 13006), not the standard 13001 adapter. Also, some port matching between the adapter and the 2991 intake is required.

It hasn’t happened already, so I already know the answer, but would you come out with a second edition testing heads?

Heads are a lot more difficult because of the variation in chamber size. Different heads on a specific engine will result in different compression ratios, skewing the results. Ideally you would like to match up the heads with an appropriate piston, but that would be a lot of expense, not to mention a lot more work than testing intakes...
