Uh, when did displacement start having anything to do with small-block/big-block? Its deck height and bore spacing that primarily make the other OEM's big-blocks "big-blocks". There is no official "line" that you cross as far as displacement where anything suddenly *becomes* a "big-block". It's the physical dimensions of the block geometry that make the difference. -Spro -----Original Message----- From: amc-list-bounces@xxxxxxxxxxxx [mailto:amc-list-bounces@xxxxxxxxxxxx] On Behalf Of Frank Swygert Sent: Monday, July 30, 2007 12:04 AM To: amc-list@xxxxxxxxxxxx Subject: Re: [Amc-list] AMC Block Sizes Some people refer to it as a "big block" based on physical size and weight (it's about the size/weight of a 352/390 FE Ford or 396 Chevy), but it's technically not a "big block" due to the displacement. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
