late update: just got put onto mopar pro shop by a fellow on the strokers group. check out http://www.moparproshop.com/jeep_engines for just about the ultimate replacement for the 258 in your spirit amx or sx/4, and http://www.moparproshop.com/performance_engines - in addition to the 392 stroker, they now have 426 and 440 inch versions of the 6.1 hemi, with up to 630 hp / 600 ft-lbs. their 572 elephant hemi is scarcely more powerful, 650/660! very spendy at over $20k, but imagine it in a '64-'65... heck, their full-roller 4.7 i6 would be pretty nice too - 265 hp / 360 ft-lbs - and it's a relative bargain at under $7000. ;^> ________________________________________________________________________ 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://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
