I showed the machinist in town the article describing the 261 with modified crank using 292 rods on a modified crank.He is no world famous engine builder but does build winning V-8 types for circle track and drag racing.he didn't like the small shoulders on the crank,his opinion was oil control problems for normal street use.Or at the minimum,excessive drag from too much oil thrown off the crank wasting HP and also heating the oil.But that's his opinion.
