Hello friends, neighbors, and all-round well-balanced peoples:
Seeing as this thread has somewhat to do with the comparison of particular manifolds, it might be a good idea to know/understand/read with comprehension (not that I'm famous for that) what IS being talked about.
The OP asked a question about, for one thing, an air gap manifold. The above list does NOT say 'air gap' in the 'E' intake list. I would guess/form an opinion...maybe even understand it to be a true fact then, that the air gap version of the Edelbrock Performer RPM manifold was not tested in the particular dyno runs noted.
Is an 'air gap' manifold different in tune/power/design than the Performer RPM manifold that is NOT an air gap? I don't know that. That they are two rather completely different manifolds suggests to me they are not the same manifold.
A curiosity: If everybody knows that a big hole manifold is the only way to go, why is it that four-hole spacers work so much better than open spacers?
Nah. I didn't ask that. I don't want any boxes of exploding poo in MY inbox!
