AlV 69 Dodge GTS project
I did a little more research on manifolds and I can see that the majority of folks prefer the stock 340 manifold over the eddy performer. In addition most folks would choose the rpm or air gap model but to quote crackedback..
"The Performer 318/360 isn't the manifold a RPM or Air Gap is but it's no slouch either.
Seen some 360's with 275hl and 9.5:1 make 400+ with a Performer, actually up to 440. Will a stock 340 do the same, likely. Pick your poison and maybe open up the port window a bit, window size in this case is overrated as to effect, and the performer will work well."
Keith, I think you're right and we have something to look forward too :)
Thanks again.
