Guest sharky Posted July 28, 2008 Share Posted July 28, 2008 Been away for a while. Cannot locate info on site so hoping not to ask annoying questions! I recently purchased 71 Monte loaded with air, etc. Believe car was originally big block but not sure. How can I tell and is AC box different from small block (currently 307 installed). I would like to install a built 427 I have on hand. Forsee any difficulties? Also cannot find trim codes, mine is 722. Where can I locate code info. Thanks.

Sam (Bones) Posted July 28, 2008 Share Posted July 28, 2008 same AC box, to find a buildsheet would be the easiest way to know if it had a big block Link to comment Share on other sites More sharing options...
MagicDragon42 Posted July 29, 2008 Share Posted July 29, 2008 The 722 trim code should be Antique Dark Saddle Elk Coated Fabric (bucket). That's the decode for a 71 Chevelle and I don't think they had unique codes for the Monte. Mike Link to comment Share on other sites More sharing options...
