What will i run? 383 91 Z
Hot Tanked and Magnafluxed block thats been bored .030 over and clearanced for the new Forged Eagle Stroker Kit. The cast steel Eagle 3.75" stroke crank spins the Forged and shot peened 5140 steel 5.7" I-beam rods attached to the Forged 4032 Aluminum JE/SRP dished pistons with -16 cc reliefs. The blocks topped with 200cc Dart Platinum Iron Eagle cast heads with 2.02 and 1.60 Stainless steel valves with a 5 angle valve job and Comp Cams guide plates, 1.5 Cnc-Motorsports Roller Rockers are pushing down the Comp Cams 987 springs good to .620 lift and the pushrods are Comp Magnum 7.200 .080 chromoly. The hydraulic roller lifters are rideing on the new Comp Cams Xtreme Fuel Injected camshaft that specs out at 280/288 with duration at .050 230/236 with the lift at .576/.571 on a 113* LSA. On top of those Dart heads is a converted LT1 intake with FMS Blue Top 24# injectors, an Accel AFPR and pushing the fuel through the system is a Walbro 255 in-tank pump.
The Custom PROM was tuned by Alvin "the chip tuneing god" at PCMFORLESS.com and that got me 95% of the way to a perfect tune!
The Bosch Platinum +4 plugs are fired by the MSD 6AL box with the 6000rpm chip then into the MSD capped and rotored stock L98 distributer through the MSD superconductor 8.5 mm wires. With the 9.8:1 compression my choice of 93 octane is going to be just fine.
The motor is pushing all the gasses out through the Hedman long tubes 1 5/8s primarys into their 3" collectors and throught the catless 3" y-pipe and out the 3" American Thunder Flowmaster Cat-back.
The Power is put to the ground through the Built 700r4 with its ~2200 stall converter, corvette servo, and Trans Go stage 2 shift kit. The 3.42 rear gears are bolted to a SLP Zexel Torsion Locking Carrier and to the 255-50vr-16 Goodyear Eagles.
The Smog/AIR has been deleted along with the EGR and the A/C. I have a great condition a/c delete heater box thats cleaned up the engine bay quite nicely.
Any Guesses?

you're only running 24# injectors on a 383 with head and cam swap?

if you can get the power to the ground (ie, some lca relocation brackets and sticky tires) i'd say mid-low 12's at 112ish. more stall and the car would go much faster, something in the 3500+ range.
