Pfordamx- No doubt you need a convertor and gear change to get your 60 fts. to improve. One thing you may want to try....stay off the two step and leave at 2000-2200. This may let the convertor 'work' a bit harder and let it flash a bit higher...might give you some insight before you spend any cash.
Also, be aware that Stockers and Super Stock cars have very aggressive convertors. You may, or may not, want that same aggressive convertor in a bracket application. Spending some time correlating similar et's/60 fts. for cars that run similar times to yours and looking at the 60's for similar e.t.'ing Stock/SS cars can be pretty revealing.
P.S. - AMX's are 'way cool.....
