Im with Mike because my 240 weighing 2600 pounds way back when bone stock except for Alum intake, 750 Vac sec carb and block huggers ran a 13.7/9 all day with a flat tappet cam Comp XE262 at about 98 to 99MPH. Considering you have the same engine setup approx subtract about 1.5 tenths per every 100 pounds heavier it is than mine, Maybe only 1 tenth but just to be conservative and ull be close. If the ZX weighs 3000 lbs, I would say 5 to 6 tenths slower depending on launch etc. So 13.7 plus 6 tenths would be around 14.3 or so. If only 1 tenth per 100 lbs then 14.1 or so. This is just an example however. My car started life running a 14.30 with Comp Cams XE292 (Way to big for the heads I had) and stock convertor. With cam change and 2000 stall it went 13.7 best on SR torquer iron heads. Then I started learning about parts matching and I am where I am today..11.98 on Engine.
Hope this helps....
