RE: A '91 GT 5.0/302 Block bored 0.030" over equals: ?
with stock rod and crank its a 306, with 3.25 stroke and 5.4 rods its a 331, and with a 3.4 stroke and 5.4 rods its a 347...
So you use the same length rods for both a 331 and 347? How does the piston not hit the top of the combustion chamber with the longer stroke crank. Or does the piston not come flush with the deck with a 3.25" stroke and 5.4" rods?
