A/B cam HP increase - bone stocker B230F ?
I've been drilling the many, many cam threads here, but none seem to answer this Q.
My 89 245, is a bone stocker with AW70 autobox (shifting well, however with recent IPD flush and new filter)....guessing right around 200K miles, since just restored my odometer with the IPD gear kit.
So how many ponies is this cheapo cam swap really worth? I've found the cam specs link here, and I gather my stocker has the M cam (9.5 I lift, 242* duration). The A/B specs are damn near same, with 10.5 I lift, 254* duration). BTW, are these duration specs absolute, or measured at 0.050" lift like USA cam specs (or some mm lift) where "real flow" begins ???
Got to change my timing belt/tensioner soon, so I'm gonna be half way or better to a cam swap anyway. These A/B cams seem to be for sale almost weekly for $50.....so If I'm going to gain some seat of the pants improvement, I will probably go for it. If the AW70 will nullify any gains and/or kill my mileage, then I might leave the snail cam in place.
Thanks in advance, cam wizards.
