Thanks for the props, I really appreciate it.
Got buried in some small projects but this coming week I will get this and the LS7 E-force projects done.
On this project it is interesting to report that the original FAST92, a SPIN-Ported 92, flowed within 8 CFM and made 498/453 on the dyno.
So far then, the FAST102 and the 102 TB look like an expensive upgrade if you don't already have a good FAST92. Again, once I'm caught up I will post all the airflow data.

Yeah it was pretty awesome! I was up there when he was doing the flow testing. Spin did a nice job on that 92 
I think the 104 is a slightly better design though.

Who ported the heads? were they hogged out to the max or are they comprable to LPE's CnC porting? What exactly is a "small 230's cam"?
Im looking for a good setup that will eventually be supercharged.

Initial Impression
Today I went up to RPM to talk with Charlie about the particulars on his latest H/C package for the LS2...come to find out he's calling it the LS2/104. After we talked about the details for a bit, Charlie made a call. And next thing you know I had the keys! 
Even though I was told it wasn't all the way finished yet, it ran great! It pulls you back in the seat whenever you touch the gas Having been used to my bolt-on LS2...I gotta say the 104 setup not only works, it works really well! You can cruise anywhere you want in the rev range without the feeling of any surging. And the acceleration in taller gears even going uphill was just smooth as can be. Which was pretty surprising to me after hearing how aggressive it sounds. Once I was a little out of town/traffic, I leaned on it a bit, and it just pulls like an un-chained beast! 
It was so much fun to drive, I had him put me on the schedule for next week
Hopefully they post some pics of what it looks like under the hood. It's super clean looking with the nice big TB, stout air intake setup, and the monster intake manifold

Hmm, I'm not that surprised at these numbers either, and they are good! I'm sure much more can be obtained with mods to the intake and exhaust and other stuff approaching "near" 600 HP at the crankshaft without the need of either a turbo or a supercharger.....however if you did afterwards......wow!!

This 243 project began life as a benchmark for our new, small bore LS7 head package. We wanted control on a fairly well maxed 243 set-up and be able to swap it over to the small bore LS7's. Naturally the first step is to produce a solid performance package based around the cathedral design (243's & 102).
This week was committed to a few other projects but next week we will finish this up. The owner will drive it and offer his input and then it is going to get swapped out for the LS7 heads and of course the LS7 intake system. Those results will be interesting.

We do the heads on our own CNC equipment. We adapted the the latest tech to the 243's and added lightweight valve train components and here we are.

It started out as Fast 102...but I believe it's been worked on a little bit.
I was just there when they were doing the final flow bench comparisons between the Spinmonster 92 and the 104.
Btw-Spin's 92 did flow very well for a 92!

I believe the extra torque is coming from the Methanol hit. Just as in the E85 thread, where the OP picked up 40rwtq just from E85.

I'm certain the meth is helping - but bear in mind, and going way back, when I did the tuning on Tony Mamo's AFR car we ended up making 484/437...and that was on a 5.7 without the benefit of meth.
