Well, I'd give myself at least an ' incompletely' unhelpful.
* I've no idea what a Mercury Tracer Trio is.
* I've no idea what the operational envelope of the proposed vehicle would be.
* Without the envelope there's no way to predict the road load.
* Without the road load there's no way to compute the required brake horsepower requirement.
* Without the brake horsepower requirement there'd be no way to come up with the heat flux, even with a BSFC map.
* Without the heat flux, we can't anticipate if any of the two original radiators would be adequate to dissipate it, or if the Metro water pump would be adequate for the necessary ( but unknown ) coolant flow rate.
* there's a heat transfer coefficient involved ( an unknown )
* will there be an air conditioning condenser coil upstream of the radiator, to add to its work?
* what is the difference in energy / distance / degree ratings? ( conductance capacity )
* are there options to coolant chemistry and chemical compatibility with existing components.
* ditch the mechanical water pump and go with a Messier electric, variable-speed pump with sensor and logic ?
I'd need some more data.
