5.9L Magnum recipe...

a friends 340 was .007" over in one cylinder.honed with new rings and it was good for 40,000 miles.it had the stock cast pistons,did not rattle and would run up to 6500 whenever asked.and it wasn't always nicely either.
keep the stock bore.why change rods?replace the rod bolt nuts and save the money for the cam and intake.
