Well, WANDER, This is going to ruffle a lot of feathers and gaul a few purists but here goes:
FORD 300
Built from 1964 - 1996, 7.4 MILLION were produced and found in every corner of the globe. Lots of aftermarket equipment, and strong as anvils, with seven main bearings, a 12 port head and 4" bores standard. Did I mention they are strong as anvils?
OK Purists, bring it.
