One rebuttal. A list member a while back stated that either he or his father discovered that in 1963-64 during the introduction of the 287 the blocks were cast without the bore size indicator. Those few blocks without the small bore size indicator were based on 327 blocks and could safely be punched to 327's 4". I have no personal knowledge of this, no reason to disbelieve either. It would have been right up Ramblers alley to use a casting with thick walls to verify the viability of the 287 and peoples reception to it before producing the actual thin wall 287 blocks. Anyone have a 63 early 64 287 without bore sizeing cast into it??? -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 -------------- Original message ---------------------- From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) > " From: d stohler <das24rules@xxxxxxxxx> > " > " > " anyway. any help would be great. by the way, is the > " 327 only a bigger bore? how far could i safely bore it > " out? how much to make it a 327? or is there more > " stroke also for 327? > > no, cranks and rods are all the same; the 327 is 4" bore and the 287 > is 3.75". cylinder walls are thick but i don't think you can go more > than .125 over. > ________________________________________________________________________ > 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://www.amc-list.com/mailman/listinfo/amc-list _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
