This is really a fruitless search in this day and age. Building an over bored 4.0L with a 258 crank will get you the same numbers, plus it is ready for the 4.0L head. The Mexican sixes had/have some of the crudest cast, heavy as sin pistons too. www.jeepstrokers.com is the forum site. Spend the time there researching what needs done to fill his needs. ------Original Message------ From: Michael C Canada Sender: amc-list-bounces@xxxxxxxxxxxx To: AMC, Rambler, Nash, Jeep and family ReplyTo: AMC, Rambler, Nash, Jeep and family Subject: [AMC-list] 300 6cyl Sent: Jul 9, 2010 11:02 PM Hi guys I have a guy locally that is obsessed about getting a 300 CID 6 that sapposidly was used in Mexican AMC cars, for his Jeep.
