I have a similar long block. I tried a Holley 750vs and a Edelbrock 440 Torker and later a 850dp on the same intake. Hands down, seat of the pants, the current Weiand tunnel ram with 660's out performs them both. I wonder now, what kind of power I am making. Thank you very much for sharing!!
I tried a torker, much less torque under 4500 rpm than the dual plane. Tunnel rams run great. I have one too, it was on a 9.5 to 1 440 I built years ago. I'm sure it'd run well on this current engine too.
