A: It's easy! Go to http://tinyurl.com/ insert the long link and click "make tiny" to have it come out http://tinyurl.com/dorrt (bad thing is it goes through mediafarm spam first) The 232 or 199 from pre '71 or a Postal Jeep for a couple years after '71 is what you need unless you change trans as well. Combustion chamber sizes are different between the two as well as oil passages/lifters. From: oconner_us@xxxxxxxxx Subject: Re: Rebuilt Engines on eBay To: mail@xxxxxxxxxxxx Message-ID: <ADVANCES62fOlaNTl2A000007b0@xxxxxxxxxxxxxxxxxxxxxxx> 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? Here is a link to his listings. Sorry, I have no idea how to shorten a link. http://search.ebay.com/_W0QQsofocusZbsQQsacatZ-1QQcatrefZC5QQfbdZ1QQampQ3BsspagenameZhQ3AhQ3AadvsearchQ3AUSQQfromZR6QQnojsprZyQQpfidZ0QQfswcZ1QQsaslopZ1QQsaslZchetniktxQQflsZ1QQsalicZ1QQsaatcZ1QQsacurZ0QQsacqyopZgeQQftrtZ1QQftrvZ1QQsadisZ200QQfposZ99202QQfsopZ1QQfsooZ1QQfclZ3QQfrppZ50
