" From: oconner_us@xxxxxxxxx " " " The only 232 I saw listed said it is for 72-74 (short block). Would " this 232 fit as a replacement for the 232 in my 66 classic? would the " head off my 66 fit this motor? They also show a 258 long block, would " that fit my 66? 1. post-'71 sixes are ~1/4" taller than earlier. 2. post-'72 sixes have v8 bellhousing pattern with starter on dist side; earlier have smaller bell with starter under manifolds. 3. some '72-4 sixes still had shaft rockers, not many. if the block isn't drilled for the oil gallery you must rig an external line. juggling of various parts can make it happen but it isn't a straight swap. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
