If my 3.31's top out in 4th at 6800rpm and 126~mph. What will the 3.31's top out at with the cobra jet intake manifold at 7600+rpm in 4th?
Was also thinking of swapping to 3.55 and don't want to shift into 5th at the 1/4 while still trapping 120mph+. The 3.55's top out at 117~mph in 4th at 6800rpm, what mph would they top out in 4th with cobra jet?
