Just  theory wise 
wouldn't it be better to have the 4.0 bore of the 302 and  whatever short 
stroke is required to reach 260?


 
Hi Phil
 
Big bore, short stroke is the way to go. All brands of Nascar engines are  
this "over square" configuration.
 
It allows better volumetric efficiency as you can stuff bigger valves in  and 
they breath better with the extra clearance the bigger bore provides. Put  
the longest rods in you can, even if the pins are up under the oil ring  lands.
