Cooling system for a 1964 Valiant with a 68 340 450 hp ?

you'll need a waterpump that has a driver's side exit so that it will mate to this AND so that you can see the timing tab on the front cover. so make sure you have the correct front cover too.

without it installed-- motor and radiator-- it's hard to say exactly what fan and clutch package you need. waterpumps have different heights, radiators have different thicknesses, non-stock motors could sit forward or back. best bet is to measure. you could probably get close with one of mancini's fan packages, but you'd be better off combining the right mix of parts to get optimal performance.

also, you should probably look into if they have a shroud for that radiator or if you'll need to fab one up.

you should be able to use all of your original pulleys.

edit: i know the MP fan kit has been NLA since forever, but this seems to be a viable alternative FAN BLADES AND CLUTCH DRIVE UNITS
