KW narrow nose with a big engine

Maybe @Ridgeline can help a fellow Michigan driver.

 

I know you could still get a narrow nose A model up into the 70's at least, and yes a 3406 or any 855 cummins were used in them. I have my eye on one, a 71, that came with a cummins, still has one, but aluminum frame and it is cracked.
I am wondering if a there is enough room to fit a 12,7 detroit and the air to air, or a 3406 E and have enough radiator capacity to cool some higher horsepower.

 

I know the engine itself will fit, where I am concerned is stuffing the air to air, plus the ac condensor behind the grill on a short hood, and cooling capacity on the skinny radiator.

 

The A models originally used a the grill densor for the ac, and I know you can get an air to air ib the wide hoods with some modifications,, for sure if you still use one, but they are not the best, especially since we had the freon change.
I actually know of at least one thin hood, actually butterfly extended hood that has a v8 cat under it, just a beautiful truck in every way.

 

@AModelCat likes those old trucks.

 

Big motors are over rated
