Using BA's venturi formula......using 6300 rpms for *max * power (2.7L RS MFI motor), I get a venturi dia of 33.67mm.
My 2.7L hot rod pulls strongly to 6500 (or so) and will rev to
7300 (MSD soft touch) but is not pulling hard there......it's an AX thing.... to avoid a shift.
My cams are Solex ( max power @ 6100) , but I'm using the 34s.
The max power RPM estimates are for the cams, irrespective of other mods, just to get one in the ball park.
