Building stock MPI 502's to replace 454's.
When selecting the MPI to use, which one does everybody prefer- the VST versions or the Cool Fuel versions? Why?

I can't really tell you which is better, but I do have some parts you may be able to use, I have a VST pump that I took off a 502 mag 97' along with the combo seawater pump and fuel pump. Took these off to put ProCharger on. Also set of stock injectors, air cleaner.
