I'm finally getting ready to install my BBC, but have a few questions. I have a complete motor tin to tin, but need help with a few items. I'm running the GM Performance parts serpentine setup for the accessories. I am trying to figure out where the oil pressure sending unit goes (on the original SBC it was on the back of the block by the distributor, but don't see a spot on the BBC), where the water temp sending unit goes (on the original SBC it was located on the side of the head but don't see any spot on the side of the BBC heads), and how to route the heater hoses (on the original SBC there was a line going from the intake to the heater core and from the heater core straight to the radiator). The BBC I have now has a line going from the water pump to the intake, a hose coming off the thermostat housing (cut) and a hose coming off the front of the intake (cut). I'm assuming I can still run the line coming out of the heater core to the radiator as before (AKA heavy duty cooling), but was wondering which line on the intake to run to the heater core (the one on top of the water neck or the other fitting coming out of the front of the intake)? I would like to use a water neck with no fitting and run the heater core off the front of the intake, but wanted to make sure that would work.....Anyone have pictures of their setup (factory or aftermarket). Thanks in advance.
