Venture a guess to my HP and 1/4 time

I'd like some input to what my flywheel as well as RWHP would be with my combo listed below.
Also a guess to my 1/4 time and mph would be appreciated !
I have about 500miles on the engine; it is getting broken in, so no dyno or strip passes for a while.
1995 Z28, T56 M6, stock 10 bolt w/3.42 gears
383 LT1 with all forged Eagle bottom end, 10.7/1 forged pistons.
Stock LT1 heads with competition valve job, back-cut valves, mild port cleanup on int and exh, FULL bowl blend.
GM LT4 Hot-Cam kit with 1.6 Roller rockers, degreed in by a local race engine builder
GM "extreme duty" roller timing chain
Comp Cams Roller lifters
Stock pushrods
Mac Mid-Length headers flowing into a single 3.5" no-cat exhaust pipe to a 2-chamber Flowmaster
Mad-Z28 mail order tune
New GM Opti w/MSD cap & rotor, MSD super conductor wires, MSD coil
Stock Throttle Body (yeah I know, it's too small)
LT4 knock module
Denso Lead-proof O2 sensors
AC rapid-fire #6 plugs
RAM clutch
Sunoco 94 octane unleaded mixed with enough Torco 110 leaded to net 100 octane leaded fuel.
Red Line 10w40 engine oil

It will run fine on pump gas.You are wasting your money.That cam is...well...small.And if its not broken in now,it never will be.I would guess 360-370 at the wheels...Times are relative to traction and driver,weather etc...

I sort of had to "choke" it with the hot cam as it is my daily driver even in WINTER here in Michigan...I drive 120+mi round trip each day to the GM Tech Center in Warren as that is where I am employed.
And yes, I have seen the next gen Camaro several times up close & personal at work....
I get my Torco 110 out of a pump....

Hey man have you been to the track yet? I'm thinking of doing pretty much the same thing to my car. My car is an A4 but should be pretty close to the same times?

compression and cam are not helping make the most out of your combo, and the race gas is not necessary. I'd guess 360-370rwhp with everything sorted out, and a nice torque curve. It won't set the world on fire, but I'll bet it's a blast to drive.

360ish cam is why. a cc306 would have been perfect for your set up with it being 383 and wouldn't be surprised if it was around the 385hp range

+1 383's tend to tame cams down.
