dont know how bushed rods makes an engine rev faster...weight of the pistons, rods and cranks usually determines how fast an engine can rev...called physics...
as far as reving a 360...never seen a stock cast crank 360 break...used to rev one 7500 rpm for two years... a bushed connecting rod broke..not the crank.
as far as making hp in the upper rpm...cylinder heads is what make hp...the short block is just pumping air thru them...
360 pistons are lighter then 340 in stock form...by over 100 gram...x 8 is 800 grams...which is almost 2 pounds...they use the same rods...and the 360 crank is lighter since it is cast..and balanced for a liter pistons...
in fact 360 pistons will always be lighter then a 340 due to the compression height of the pistons with the 360 having a longer stroke and both engines using the same deck height blocks.
take a 5 pound hammer and swing it...and take a 2 pound hammer and swing it....which one swings faster???? 2 pounds.....physics...
