I know the LT1 (92-???) engines had reverse cooling flow, but I have seen dates that include some of the L98 motors.

I have a 83' 350, 4 bolt main short block. I have a TPI unit from an 87 Camaro and I am buying a set of world heads for my setup and I was going to use the water pump and all pullys and brackets from a 86 Camaro. Is the water pump from an 86 Camaro normal flow? I need to know this before I buy my heads.
