10-4, the early model rods are supposed to have the correct size rod ends for 351 pistons if you can find them. Not sure what years...
Exactly my quandary...what years do I need to look at?
and if I do manage to find them, get them to clear everything, valves, head clearances...etc....will they take this 300 out of the realm of running on pump gas?
I wouldn't sweat finding early rods, it's no worry to have rods bushed to fit.
There are actually a ton more options for piston volume/compression height with a 351 piston, so whether or not it would run on pump gas depends on deck height, head volume, etc.
