Take a look at the pump that is on the engine now. It's fairly easy to see the difference between the long style and the shorty.The long pumps have extra cast on "fins" on them that are easily visible. The short pumps are pretty much smooth. You can also do a little measuring to see which one you have now.
I personally see no need for any fancy type pumps. Hi flow is ok, but you would also need a hi flow thermostat to take advantage of the pump's flow capacity. Another issue with a hi flow pump is pushing the coolant thru the radiator too quickly. If the coolant runs thru too quick, it doesn't have time to actually COOL....it has to be in contact with the cooler outside air going thru the rad to do any good. The best bet is to use a design the same as OE used. You have to treat/repair the
entire cooling system to get the best results. This includes making sure ALL of the seals for the rad and shroud are in place, and in good condition. If this is an A/C car, be sure the condenser isn't packed full of road debris(bugs, ciggy butts, cats, etc.), as well as the radiator. Make sure you have a good front air dam. The big block cars used an air dam that was deeper(longer) than the small block cars, so be sure yours has the correct dam.
Lots of heat, and a small engine compartment on these cars can make cooling them tough....but it can be done.
dam spel chek...
