Engine Combo Question

Well Im thinking about buidling a 426 small block stroker motor, using the Ohio Crankshaft kit. Using either a 360 or just a 340 we already have. I really wanna put the Indy Cylinder Heads 360-1 heads and Intake on it, along with prolly a 1.7 roler rocker for roller cam we already have to make it around
.750-.760 lift or so. More than likely itll be backed with a glide. It will be going in a dart, weighing around 2900-3000lbs drag car, full funny car cage, 4 link, 14.5-15w * 32 slicks, dana 60 w/ 6.17 gears. What Im wanting to find out, is how much power you think that combo is capable of making and what assumptions do you have on what the car may run?? Were looking to realistically run 6.20s -6.30s somewhere in that neighborhood, maybe a tad bit faster...Any input or conversation or opinions n what might be better will be greatly appreciated, thanks guys
