E cam/ F cam/ WG 1087 cam?

[FiveOh 86LX]

My setup is gt40p worked/ported heads (2.02 int, 1.6 ex), performance edelbrock intake, holley 650 carb, 3.73 gears, 1.6 rockers, 89 gt forged internals.
I'm trying to get the best E/T 1/4 mile and/or best H/P and Torque. Intentions of shooting 150 shots of NOS and eventually a power adder... I hear turbo's and F303's are a good combo, or a WG 1087 and a S/C works plenty good... Also heard of Anderson's B-31??... For now it'd just be the h/c/i combo, maybe a few months before nos, and then probably a year later I'd get a power adder...
Any opinions/predictions on power/times (86 Notchback)

I would just see that short block is alright first and then go from there. A 150 shot of nitrous and a s/c with a decent hci won't last too long with the stock block, unless you were thinking about nitrous and then switching to a s/c. What ets did the previous owner get with the combo that's on the engine now? What do you have as far as suspension mods?

All the times are only 1/8 miles, at ranges from 76-78.9MPH times ranged from 9.00-9.8.... Seems very off for what the mods are. The more I think about it the less probability I'll be shooting nos. I've heard people say my biggest limiting factor is my performance edelbrock intake, any suggestions on different ones (it is carb'd)? As for now it'd just be a H/C/I.
