" From: Frank Swygert <farna@xxxxxxx> " " [] " I'd build the engine to take advantage " of the extra leverage of the longer stroke -- a low rpm torque monster, " out of cam by 5000-5500 rpm. The one or two guys I heard of doing this " for high rpm drag engines filled the block to the bottom edge of the " welch plugs (freeze plugs) for added strength. There should still be " plenty water jacket to even drive it on the street filled like that, but " make sure you have a good cooling system and a temp gauge. thinking idly about it - should be perfectly safe to fill up to the piston crown at bdc, 3.68"-odd down the bore. below that will never see combustion heat; the piston's in the way. it will see piston friction, but with the rod as vertical as it gets, not much. but as greg said, probably excessive for the street. ________________________________________________________________________ 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@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
