This year I am transitioning from nitrous to ProCharger. So, I sold my old 403" LS2 short-block and I am building an LS NEXT II, aluminum full-skirt block based 427" short-block for forced induction.
Here is the breakdown:
Dart LS NEXT II Full Skirt Alumunum Block with 1/2" main and head stud upgrade - 31947211
Callies Dragon Slayer Crankshaft -APO31T-DS with 58x billet reluctor
The heads arriving. I have already run these on my old nitrous setup, so more pics to come when they are cleaned up again. The Dart Pro1 LS3 heads are excellent to start with, but even these great heads picked up nearly 3 MPH in the 1/8 mile when Frankenstein reworked them. Amazing.
Other supporting items coming soon are:
ARH 2"x3 1/2" stainless headers
Circle D 245 mm 2c torque converter
Extreme Automatics 4L80 with billet everything including billet manual valve body with brake.
Aeromotive 4 port regulator and Aeromotive Eliminator fuel pump.
Some more bars on the cage to make it 8.50 ET legal
Ummmmmm yeah; might be a problem when this thing runs twenties.
Love the CSU blo thru stuff. Flat out works !!!!!!
Yeah, if it tries to go that fast, I will turn it down. I don't want to go that fast in this chassis. That is one of the reasons it has the F1a94 and not the F1x.

Looking forward to results.
Will you be able to post Flow#s on your Heads?
They were never flowed. I don't know if Frankenstein has flow numbers for this head program or not, I would have to ask.
Rock hard over the blow through, though I have yet to achieve completion like A.R. did.
Do you drive this thing on the street still?
Absolutely! It is primarily a street car. If I were to have a racecar, I would use something light! LOL. When it is on the road, I drive it about 2-3 times a week. I love driving it. It has overdrive, full interior with factory console and seats, power steering etc.
