This is a listing for 40X engines; mods; dyno graphs; and track times if available. So far this listing is what I could find with the search feature. If anyone wants to add to a post that I found or add info about your car that is not included feel free but try to keep the chit chat to a minimum, or use the PMs.
By request here is a breakdown of the dynos in the thread so far. I left out some questionable ones. Average HP________Average TQ 507.90______________481.25
Least HP___________Least TQ 432__________________425
Most HP___________Most TQ 601_______________538
I was in a hurry but here is a small HP/TQ graph, blue = HP purple = TQ
Thanks
BTW here is my set up...when it is tuned I will post my results, currently most of the parts are on the floor of my garage. The motor will be here next week or so.

Car made 456/445 on the dyno and at the track did:
I borrowed 3 yr old slicks and finally got to the track...not many cars there so did not wait more than 10-20 minutes (longest) between runs...almost hot lapping. Car is right at 4k with me in it.
First pass I was like WTF over:
the car started in second gear (A4) and stayed there the entire 1/8th, anyway here it is:
Next...did some tuning on the trans
60' 1.7211 (manually put in 1) spinning through the 60'
330 4.8790
594 7.0048
1/8 7.4810 @94.5 (better) but can the car back it up?

at the suggestion of a member of another board, he said to retard the cam to make more power as his opinion is the cam being ground 5* advanced is limiting my peak hp at 5700 rpms. well, it didn't go as planned.
Mine did 440hp 437ftlbs. & 620hp & 637ftlbs. (TNT 200 with no bottle warmer & crappy bottle pressure) on a crappy LS6 intake & stock TB with no underdrive pulley. The car had about 500mi on it at the time. List of mods include, FFHP 408ci, Patriot Stage III LS6 heads, Comp 244/248 .612/615 113lsa LS6 intake, stock TB, Pacesetter LT's, open cutout, Rossler 4l60e, TCI3500, 3.73's. 10.7-1 CR. The LS6 intake setup was creating alot of vaccum so it was chocked up real bad, havent had a chance to redyno yet.
Ive since added the fast 90mm intake & the NW 90mm TB. That should open it up a bit, Im also going with a higher CR, somewhere along the lines or 12.1-1 or so.

Well guys, technically my results have been posted by Brandon Boomhauer. However, I bought his car recently, so I guess I'll re-share the info...
-Built by Erik @ HPE
-10.96:1 compression ratio
-Stock 241 casting heads
-LS6 intake
-Comp XE-R 244/248 612/615 115 lsa
-Pacesetter 1 3/4" Longtubes into TSP True Duals w/ x-pipe
-42 lb. injectors
I made 432 rwhp and 431 lb. ft. of torque. I recently ran a 12.2 @ 119 on street tires as well. What do you guys think about all this? Should I be happy with it for the time being? I know when I throw a set of heads and an intake on it, it should make a huge jump, hopefully over the 500 mark. Let me know what ya'll think. If you need any other info, lmk. I'll scan the dyno sheet later on today. Thanks, Alex

My 408 dyno numbers were low but I think I have too low compression, and a shitty intake. Mine was 450hp/440tq. I have a stock ls2 90mm intake, and I did the math yesterday and Im at 10.4 to 1 compression. I have patriot 72 cc stage 3 heads w/2.08 1.60 valves 225cc runners, and a Texas giant cam. I think by going to a 64cc stage 3 with 225 runners I would be in the 11.3 to 1 area, that should pick me up 20-30 rwhp. Im also going to get a fast intake, maybe between the two I can see 500rwhp. ????????????
Maybe more compression to get 500, IMO it will help.

Well heres the setup LME put in it,wiseco -8cc pistons,.013 .015 out of the hole.I installed unmilled AFR205s,GM .054 head gaskets.If I calculated correctly I should be at 11.15cr.The cam has no advance to it,I installed it staight up.I was thinking the cam I had in mind 238/244 110lsa .639/.642 would it either help or hurt me.Whats the magic cam for a 408ci?I know the heads are good for at least 500whp,just need to get it right.

Includes:
Eagle 4340 4" Crankshaft
Eagle 6.1275" H-Beam Rods
Diamond 4.030" Bore Pistons
Comp Cams Replacement Lifters
TSP PRC 3 LS6 Heads w/Hand Port
TSP PRC Dual Springs Rated To .650 Lift
TSP Giant Cam ..248 .254 .622 .613 114 lsa
Custom Base Tune From Brian @ PCM4Less (Sucked but got me to Atlanta for G10)
Comp Cams Double Roller Timing Chain
MLS Head Gaskets
Every Nut and Bolt is ARP
90/90 (Intake Manifold Hand Ported By Me.)
1 7/8 Kooks Ceramic Coated Stainless Longtubes
This is all N/a and with compression under 11.25:1 on a 93* day with 65% humidity, full belts and full exhaust.
A/F was in the 10's under 3000 rpm's and 11's until 4750 rpm's. It never got above a 12.6...until 6600 rpm's...I think it's safe to say there is a nice bit hiding in a tune.
532 RWHP 485 RWTQ
I'm sure torque is down because of the larger headers but I wanted to get them and suffer the loss n/a for my gains on the hose. This motor will be recieving a 250 progressive direct port. Compression was also lower than optimal because of the heat that we get down here in the SE part of the country. It still put down decent numbers and now I'm not so worried about detonation with spray later down the road.

02 WS6 408 pump gas, mufflers and on ET Street DRs:

I'm pretty happy with that considering it is through a loose converter/th400. I look forward to getting it on the track and seeing how it compares to last years times. Haven't sprayed it on the dyno yet - wanted to get the motor tune in good first.

Made 425/445 with 12.1-12.9 AFR. Supposedly nothing substantial was gained by leaning it out. I thought my numbers were decent until perusing this thread. Any ideas?
I'm sending my heads out tomorrow to get ported and a 2.08/1.6 setup so that should help a bit. But I'd like to get the lost power issue addressed now before the heads get back so I don't have to extend this issue
I've got a 408 built by Texas Speed... AFR 205 heads... 244/248 .612/.615 115lsa cam.. 1 3/4 pacesetter LTs, ASP underdrive pulley, LS6 intake, 3" ORY, Hooker catback... along with the Racetronix PnP kit & 42# injectors.. and a SLP maf... stock TB. It's an Auto with 3.23 rear gears & 3800 stall converter. It was trailered to & tuned by Speed Inc in Schaumburg IL when we were finished putting it together. It put down 450hp/425tq with zero miles on the motor.... running a 'low' 10.2:1 compression ratio... on 93 octane.
I'm hoping with a FAST 90 / NW 90 setup... it should pick up a couple more ponies. It falls off some at the top... think it's running out of breath.

Here's mine. can't believe I hadn't posted it already :lol
iron 408
M6, 4.10 gears, dyno with 28" slicks
12.8:1 comression
CHS ported 5.7L heads flowed 293@600
FMS 246/250 .632
1 7/8 QTP headers
all the bolt-ons
Fast 90/90
stock Rockers
Melling lifters
550rwhp 515rwtq
It dyno'd 545rwhp and 535rwtq with 1 3/4 headers
I just swapped over to a Vic JR intake and will dyno it saturday. hoping for ~570rwhp. will be at the track sunday, hoping for 10.0's @ 135. I never quite had everything worked out with the old setup, but I'm sure it would have gone 10.3's.
up in flames... 408 12.85:1, M6 10.52 @ 130 1.42; 10.12 @ 137 on a 100 shot. 3469 lbs

Well I have a FMS408ci of almost 2 years now if I remember correctly. 6.0L FMS/Meaux heads with 11.75 to 1 compression and 2.05 x 1.60 valves. You can see my dyno's in two cars.. F-body and Y-body... 563/518
No electric water pump or shortbelt mod. Small mixture of 104 octane with a huge mixture of 93 octane just for safety purposes. Now dont forget my heads are like 3 FMS updates behind.
