I was just browsing thru a catalog, and they have a TBI spacer that *claims to add 22HP and ~25 ft.lbs of torque. Its $65.00, and am curious if anyone has added a gem similiar to this...or if its a bunch of hooey. I was also lookin at a dual 27" electric fan set up, that 'guarantees' to add 25 HP ($350) for a 5.0 (huh, my 305!) I know its been brought up, going electric fans...but don't recall any real praise or bad mouthin'. Live in san diego, and dunno if electric would be wise for desert trails. Thanks for the input!
