Hello Guys,
You guys have been so helpful with all my questions - still waiting someone to swat me for being a PITA.
I've been weighing my options with using the truck water-pump with the goofy up-and-over hose barb, or using the F-body water pump with spacers and minor changes to the idler and tensioner with a kit or this Holley 22-101 water pump which will apparently work with my existing LM7 accessory drive where the alternator is up high on the driver side on a heavy cast bracket it shares with the power steering pump. I've found a few comments on car parts vendor's websites that the Holley water pump has a porous casting - two individuals said the water pump leaks THROUGH THE CASTING.
Has anybody used this water pump successfully with a truck engine (4.8/5.3L)? https://www.holley.com/products/cooling/water_pumps/parts/22-101
Cheapest option is to go with the original truck water-pump and find a long-arse hose to the radiator. Second cheapest option appears to be the Holley water-pump. Least attractive option is 3/4-inch spacers, f-body water pump with f-body tensioner and idler pully relocation (LSX innovations parts WP11, IR10).
Seems the $215 cost of the Holley water-pump is cheaper than buying a new f-body water pump and all the junk. Plus, the spacers give more places for a leak!
Additionally, has anybody reduced the pressure of their power steering pump with Borgeson Universal 899001? I bought a brand new g-body power steering pressure hose because I heard it will screw into the LM7 power steering pump; I haven't verified that yet. My coworker (drag racer) says the power steering pressure on the LS is just fine for the g-body steering box; another guy dropped the pressure with the kit I mentioned, but that may have been for an older car (not a g-body).
Best Regards,
Michael
