Not looking to resurrect an old topic...but I get that the stock 5.0 HO block's pump IS reverse rotation = pulley spins counter clockwise ... so standard rotation pump= pulley spins clockwise,like the rest of the accessories thus regardless of which direction the pulley spins,the impeller on the pump moves the water in the same direction..so..in from the lower rad hose,thru the block and out of the upper rad hose into the rad and spinning a reverse rotation pump the opposite way(clockwise) would result in no water movement.
So question is.. if I fit the standard clockwise WP to the 5.0 HO block with a GILMER set up, rather than my current serpentine reverse drive set up..are we are in the zone for this application...I understand that the pumps are identical apart from the directional impeller..but my concern still is...IS this a direct bolt up with hoses in the same place and do the bolts still line up...or do we need to modify the timing case housing...and any one got a part number for a compatible 5.0 HO standard clockwise rotating WP suitable for the gilmer pullies
