soooo on your build -- how much vibration ,
oil consumption and engine wear are you willing to tolerate>?
with the rod ratio and required pistons-- a 427W can lead to cylinder bore wear issues and
oil consumption over the long-haul.
For instance - I am not a fan of ANY stroker piston where the
OIL CONTROL RINGS intersect with the piston pin hole/bore, this leads to oil consumption and dirtier than needed exhaust. ( Note: I am not a treehugger by any means but in automotive engineering this is the equivalent of using match-heads for sparkplugs. )
a 402-408W (still with a 4.030 bore) might be a healthy long term , powerful alternative that would run cleaner, burn less oil, and last longer.
My 5cents worth.
