I Notice you skip over all the one's that it had a hard time making 300 hp and less than 1 lbs-ft per cid which is insanely inefficient post #43 finally gets around where 318willrun's engine is ish, then yes after a decent ported head it barely cracks 1 lbs-ft per Cid which is still terribly inefficient. But yes wakes the engine up hp wise (but also barely cracks 1 hp per Cid) and yes would make a good engine for the truck, but will 318willrun build it to that level and if so what would the Magnum do with a similar ported head and cam ? Probably similar hp.
