Have you ever ran one of these Tarantulas before? Am curious about the potential, I hear that Edelbrock did a lot of R and D on these manifolds and they were actually better than the first Torker 340 intake but really only suitable for gears of 3.91 to 4.88. There is another user on here that put a torker 340 first gen on a pretty streetable 340 build and picked up .3 or .4 in the quarter over the much vaunted and praised RPM Air=Gap manifold.
