" From: "Thomas Garner" <Tgarner@xxxxxxxxxxxxxx> " " " I do like the idea of the 4.0 head. " What about the 4.2 head instead? frank answered that, but i'm starting to like jim's idea of a '71 258. '70s-'80s have marginally better ports but '64-7 has the best chambers. i'm thinking your head on a '71 block with '80s pistons [they're taller for good 'squish']. is the '71 crank actually different from later 258s? it would be in the flywheel bolts... maybe a '71 232 could be rebuilt into a 258 with later crank and rods. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
