Stroker intake question and guidance, mainly guidance.
My vote is single plane.........the argument of giving up bottom end cracks me up; what are you calling "bottom end"??.....what kind of a torque curve are you thinking about......electric motor style that has max torque at zero rpm?? Too much "bottom end" is hard to lay down in a corner, you break the tires loose, you could end up loop-de-loop and they don't have a lot of guard rails out there and canyon walls are very unforgiving.
For the record, my 360 has an M1, 557 cam with 1.6 rockers, Hughes fully ported Eddies and I never felt I was lacking 'bottom end", at times I thought about killing some of what I had so I could hook better.
