Rusty,    The p port sucks in a lot more air than does the side port. =20=

I don't know what the stock timing is so I don't know how much is=20
timing related.  I think it  just a much more efficient  to pulling air=20=

in directly than through a convoluted passage through the side housing.=20=

Rusty,    The p port sucks in a lot more air than does the side port.=20
I don't know what the stock timing is so I don't know how much is
timing related.  I think it  just a much more efficient  to pulling
