" From: Frank Swygert <farna@xxxxxxx> " " I wouldn't mess with the block at all, just cast a new cross-flow " cylinder head! I wonder how close the Aussie slant six hemi head " is to the 4.0L bore spacing, bore, and head bolt pattern? Now if " that could be modified to fit you'd just about have what you want! not close at all, i think. the slant is a small small-bore [3.4"] long stroke engine, but the aussie hemi is a large small-bore long stroke much like the old mopar flathead, which lasted into the '60s and had similar displacement. it was originally designed as a dodge truck engine - presumably to replace the flathead - but never saw production here before it was shipped off to australia. " A new front with double overhead cams (or even a single!) would be " nice too. there's the slim possibility of modding an old Pontiac " OHC head to fit, but like the slant six hemi I doubt the " bore/spacing/bolt pattern are close enough. Pushrods for the hemi " might be as much "fun" as modding the front for the OHC belt and " cover. there's interesting chevy bore-spacing legacy in that poncho. the sbc bores are on 4.4" centers; the 194/230/250/292 inline also has 4.4" centers, so the ohc derivative does too. but the 2.8/3.1/3.4 v6s also have 4.4" centers, and i saw where someone was trying to cut and weld 2 z34 dual cam 4 valve heads into one for the ohc6. bonus win - bolt pattern is identical too. it's very unlikely that the amc 6 shares spacing and pattern with any other engine. i would've hoped it had something in common with the amc v8... ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
