In order to get the best transmission options you definitely want a 72+ block! Of course I think you can bolt an iron BW (M-11/12) to the air-cooled (M-35/37) bell housing if you wanted to. A T-96 sure wouldn't last long! That's one six I'd consider bolting a 727 to, but a 2WD 998 (used behind 304s, or use the output of a 904 on an Eagle/Jeep 998) should be sufficient since you're not doing 25 pounds of boost and over 6K rpm. A 72-mid 80 block (cast iron intake) would be best as they are slightly heavier than mid 80+ (aluminum intake). Lucky for you the bore is the same for the 199/232/258, and the manual trans crank flanges are the same. There's a bolt on adapter for the TF trannys, but the adapter that requires machining is the best to use. The strictly bolt-on one that needs no machining has a 1/4" spacer between the bell and engine. ------------------ Date: Wed, 13 Aug 2008 17:37:41 -0700 From: Tom Jennings <tomj@xxxxxxx> For me, I'm gonna build a stock 199 bottom end -- new or old pattern block is still TBD -- and put the radical head on it. It's got massive porting and polishing, big valves, custom cast turbo manifold ready-to-go. Yeah 4.0 EFI is "better" but no way it'll look as cool as this setup! -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
