If your looking for efficiency, gas mileage, and engine longevity stay with the AA. An A would probably increase your top end RPM by about 150 to 200 rpm. However, that depends on what your horsepower torque peak is relative to RPM. With that motor I wouldn't go smaller than an A in a stock configuration.

spectras only thanx for the Ford info ..
those Ford Motorsports motors sound good, but it looks like I'll be rebuilding the one I have when the time comes. Those are a little pricey for me :-)

Hey jetbug,
Check out cpperformance.com inside online catalog then jetdrives and look for intake/loader grates.......lots of good info. The loader grate I beleive is to force more water into your intake which will help load your impellor and decrease cavitation in these monster bowties....Not sure how it would work out up here with all the shale and rock.....might end up at the bottom with the fishes
