That combo should go 11s NA, get it to cut low 1.5X 60ft and it will. I would change the cam to a mid 500 lift solid cam. I had the comp XS282S in a 360 with X heads, it did it. On a clean 100 hit I'd guess 10.80's. For shocks, look into Viking performance shocks. Very nice stuff.... and they say I never help fellow mopar guys ;)
