There are plenty of good intakes out there. What have you done to warrant an intake swap? A stock gt40 is good to about 400-425 HP, yours ported is maybe good to 450. Thats alot of hp for street driven rides. I recently installed a cobra and cam on my steed, I ported the lower and heads myself and have no probs w/ flow, @ least that I know of. I've never dynoed my ride, but to get the correct air fuel ratio it is a good idea. I personally would leave well enough alone. John
