i'll run hydroboost at a later date but the one from my donor trucks leaking everywhere and a 1/2ton booster line was 5$ at a junkyard and fits great.just had to pull the plug from the back of the intake and install.
also got the pump fitting and pressure valve from a 70 k10 while i was at the yard so i can use stock k20 power steering lines and have stock steering feel(i hope).the valves miked out the same and it all bolted right into the 2000 pump.i've got to say i like the interchangeability of chevy parts!
i'm thinking i'll run some hard line under the fan to the auto trans cooler ports on the rad for the engine oil cooler and put some barb fittings in the cut 6.0l rubber cooler lines to join it.
