2)8-blade hi-flo pump with an anti-cavitation plate, and matching Hi-flo 195 stat,
anti-collapse spring in lower hose, 50/50 coolant, semi-restricted bypass hose,
I don't think the op mentioned what water pump he was running. The 8 vane w/plate would be the first thing to install, if there was a 6 vane on it currently.
