Well said , I have a 77 886 Power Wagon ambulance which still has its original 318 with under 50,000 original miles its very heavy , cast iron tranfercase etc , and full time 4WD.
I installed a Isky RV/TOWING cam and vintage Offy dual port intake and it really woke it up.
You would have thought the 360 would have been mandatory in such a heavy vehicle but the old 318 gets the job done bottom-line.
