Maybe instead of going from a 6262 to a 71, maybe change to a 4 bolt and you will be dead nuts peak efficiency.
from what I have seen the car may not go faster with lower backpressure as each combo needs a certain amount of backpressure.there are so many variables and we have cars around here that run have for a long time either way.whats nice about the 4 bolt is there are a lot of options out there so one swapping them out of measuring bp would eventually hit the combo.
