[FED 387]

we have always taken the "stock" type pump out and modified it ... What we have done is remove the impeller and grind off every other blade on the impeller.NO restrictions in the thermostat housing restrictors/thermostat shell whatever. Put new seals,gaskets & bearing in and re installed it ---we can drive the car into the staging lanes, do a burn out make a 1/4 mile pass drive the car to the scale, fuel check and back to the trailer and never got over 190*--- course ya shut it off at the scale-- fuel check lotsa pushing but it still does not get too hot---- using a stock 67 Camaro 6 cylinder manual trans radiator/aluminum sbc pump with a stock 67 Camaro 6 cylinder fan shroud and a aluminum 2-3 inch fan spacer and a fiberglass fan with a Moroso style electric motor drive to the pump also a long style pump or a short style pump with the aluminum spacers-- do not use a V8 shroud cuz the shroud is not deep enough for the fan to get close enough to the radiator and a manual trans radiator does not have any cooling stuff in the end tanks for the auto trans.also the 6 cylinder radiator takes lotsa weight off the front end of the car ---SBC super modified class car----works for us
