Water pump inlet preference

I'm starting fresh on my 351W build, so I can decide on pass side or drivers side water pump inlet. Once I decide that, then it dictates radiator, timing pointer, etc. I'll only be running an alternator, no other accessories. Does anyone have a preference or is there a benefit one way or the other? From my research, Ford switched to drivers side in 1970.
 
:wstu x2

depending on how the core is set up, some radiators with the inlet /outlet on the same side lose about half their cooling efficiency. it would need the baffle (or whatever its called) to evenly distribute coolant across the radiator to be efficient.
 
There are crossflow radiators with inlet/outlet on both sides and separated across the middle, so the fluid passes the core twice. No experience with them personally, but seems like a good idea.
 
All depends on how you will use the car.
Daily driven , street performance or track use.
Before "crossflow radiators" comes in order , you will need to decide if you go for a 2 , 3 , 4 row radiator , copper or alu , and certainly you will install a fan shroud .
Is the fan a fix one , flex one or a one that is thermostatic engaged .
The cooling capacity of a radiator is determinated by its seize and/or construction(see crossflow ones )

A 2 row with fan shroud and flexfan can be more efficient that a 4 row without a fanshroud and a fix fan.

It all depends of what your intensions are.

I have a 351W 4V engine (no mods ) and I have Alu 2 row ( 2X1inch) radiator (pass outlet ) with fanshroud and a thermostatic engaged fan.

Hopes this can be of any help.

pass in and driver out is better then pass in and pass out with the same kind of radiator.
Thats what CMAYNA ment.I think :hide
