thanks for the reply
"so I am guessing you want
TORQUE... which would be the Edelbrock Performer RPM dual plane manifold...not the Victor Jr."
so would this manifold give me a loss in hp #s from what i have now, what are the diffrences in a dual plane or a single plane
i would have to say yes to the torque, i dont plan on making any new speed records, i just want it to pull hard off the line and have a good strong pull up through the gears, but also dont want to loose too much HP in doing so
