Now the big question.
Did you hog out the intake manifold?
Otherwise that larger throttle body is worthless as the opening size is now the restriction! Food for thought...
Even the SVT 60mm TB could benefit from this port matching... Also I don't see how much larger you could go. 10mm is a ton to try and hog out... Don't remember seeing that much meat, but then I was looking at it compared to the 60mm unit???
