+12HP.Just saw a K&N sticker on a Nissan Altima.
+12HP.
I bought an old 72 Biscayne just for the drivetrain (400 SB, Turbo 400, paid $200). When I had my 69 F100 Ranger I installed a HAYS clutch in it. It came with a very nice, large decal (about 12"X 2.5"). I put it on the Biscayne's back window. Man, I received so much ribbing about that decal and how it shouldn't be on my Biscayne because it had an auto trans.If it actually had a K&N.. -20HP due to not being the optimal OE design![]()
