Back from the Dyno
Just got done with the H/C swap and tuning. Though Id share the results. Before the swap, I was at 304whp/291wtq.
Cam installed was a custom grind 220/228 .578/.586 on a 115*LSA. Heads are fully ported 243's by WCC, w/ stainless steel valves and decked to 63cc.
Final readout was 387whp/337wtq. The cam was not exactly what I wanted, but I am impressed with a 83whp increase and 46wtq to say the least. I wanted a 222 or 224 int. and 114 LSA. But the specs are very close and I will have no trouble passing the sniffer here in Cali.
Still have yet to do long-tubes. So easily a 400whp car if I go that route.

Auto with 3.42 gears and a 3200 stall. That soaked up some of the numbers I know.
(RPM stage two diff, Yank billet SS3200)

Yes.. I suppose it is important to mention that I had my FAST92 port matched to the ported heads 
, And I already did my port match of the LS2 TB to the FAST before all this..
Other things to mention may be the ATI damper, BBK shorties, CHE rockers, titanium retainers and locks, x-pipe and axle back straight pipes.
Im itching to do the LT's now. I want to break 400 on this un-corrected dyno, and despite the gears and stall. A true 400 making it to the ground in addition to all the other goodies working together makes for a very fun car.

I know it's an AT, but your numbers are really low for a H/C/I car. The addition of LTs to your shorties should be a pretty small gain. Your cam selection is conservative, but OK, so I'd guess the heads are to blame. Couldn't tell you how, especially since they're 243s, but stock (headers only) LS6s can beat those numbers, with stock heads, and the smaller LS6 cam.

OP if you're just wanting an uncorrected 400rwhp dyno sheet, just wait for a cold day and redyno

This heads and mild cam package made 83 whp. Thats actually quite impressive... This goes to show why I hate the numbers game from DynoJets and the like. I dont want to get into this again. But right now I can take my car over to Cunningham motorsports nearby and dyno out 430ish whp if I wanted to.

Im waiting on a drag suspension kit from Pfadt, so hopefully it will come while I wait so I can race with a set of drag specific coilovers, poly control arm bushings, and the heavy rate rear bar.

The car got a bit louder, but on the 115LSA the idle is not really choppy. More of a fast pased "thump thump" but continuous without break. Both the LSA and the int. duration are very conservative to insure it passes. I have seen 224 and 114 cams pass here. But went down a few to make sure.
