there is a reason i dont have a dyno in the shop , too many ideas at hand ! I will stick to the 2x4 setup for the street
Excellent choice. You will like it but revive all of the Holley curse words you had forgotten about.
The sb 2x4 pulls HARD and depending on the cam, idles like a pussy cat.
Earl: there is that 2x4 t/a 'windsor' manifold mated to the special cast small port Boss 302 heads so is anyone sure exactly what COULD still turn up as far as manifolds go? I wouldn't be shocked if there was that Boss 302 t/a also cast for C6FE 289 heads, maybe just more stupefied?
This is like Rocky and Bullwinkle. "Hey Rocky, watch me pull a rabbit out of my hat?"
