Here’s a question for you. I’ve done all the google searching… since I’m not running the SRV valve on the 6.4Intake, how would a 6.1 intake compare straight up? There’s one for sale locally to me…
Everything I’ve read says the SRT8 intake is better but that is due to the the SRV function. Nothing to infer about the SRV disable srt8 intake vs a 6.1 intake….

My gut says…it depends. :p

If you want high RPM horsepower, my bet is the 6.1 intake will out perform the 6.4 intake with the SRV locked out. The reason I think this is because (as I understand it) the lock out locks the intake in long runner mode.

If you want low end torque, I think the 6.4 with an SRV lock out will be better. For the same reason.

There’s my uneducated guesses. Take them for what they are worth.
