Another BB intake selection?

I am guessing with the 4.30's and a 28" tire your combo will be fine with the M1. Are you hitting the NOS off the line or later in the run? The NOS can make up for the low end loss till your up on the RRR's to run the M1.

Guessing your heads are ported because much more then a 500 lift the stock head run all the same.

Cheers Don.
