Had this idea since i blew up my 98 zrt this year. Will a thundercat 1000 (same chassis 96-98) swap straight in? What about the next few years? Was the 900 thundercat a twin? (99-?) Anyone have any input that might help me get some more motor than the 600 w/o alot of custom fabbing? The 600 was good... but as you all know, theres no replacement for displacement! Also had the idea (though small) about swapping out the tub/hood on the 98 and trying the fit on the 99-? ZR? Were the front suspension dimensions the same from, say...96-2000,2001?
