What is the absolute largest radiator that would fit in my truck(I had a thought of putting one from a 1994 f350 that had a 454 block in it) but I am sure that is far to big but just for knowledge sake what is the biggest that will fit.

 

i think the location of the inlet/outlet and all that stuff is going to be a bigger deal than physical size...

but ill let someone else who knows more about this subject to tell you for sure ha

 

Why would you need a radiator that big?

 

dunno it was just a thought me and my friend were trying to think about it on our 5 hour drive back from Houston.

 

There is no need for it. Just extra weight and work for no reason. The engine will still stay at 195* but just take longer to reach it. You want to be in closed-loop ASAP.

 

ahh, I see, that makes sense

 

Also if the coolant takes to long to heat up it will throw a code thinking the thermostat is lazy.
