Bringing this thread back from the dead since we have some recent engine dyno comparisons. Glad to see the competition is hot these days on the LSX front!

Westechs dyno is spot on....it used to be about 2% high a few years ago due to an inaccurate weather station, but that has long been reseolved. My 346 rolled 475+ on six different dyno's in two different states and only losing 75 from crankshaft to rear wheel power is pretty good even for a manual trans car (with power robbing 3.90's in the rear as well). Also, the math dictates that it would take every bit of 550 HP to propel a 3450 lb. vehicle to 124 MPH at 1500 above sea level.
The car ran the MPH to back both the rear wheel and observed flywheel numbers and my current 383 (which made 60 more flywheel HP and 60 more RWHP) did just the same by running the number at the track eclipsing my 346 by about 5 MPH.

Last time I checked 507.9 is higher then 505. I could be wrong but I think it is.
507.9 with LS6 heads through a 12-bolt HD Pasi with 4.56 gears
505 with AFR heads through 9" Spool 4.11's
HM.... I honestly don't think you have the world record do you?
I'll let it slide since this was posted over a year ago

Where do you live that those cars are deep into the 10's w/ NA stock bottom ends? I bet they are gutted to ****, hell give me a car that weighs 3000lbs w/ 470 RWHP and a good suspension and I'll click 10.30's-10.40's off all day

Ur right I have not run anything worth ****.
I guess running 10.56 @ 129 with 477 HP and 3350-LBS in a street driven WS.6 isnt worth ****.
I cant wait to hit the track with 507HP...

We backed up those numbers with the 10.40s at 140, broke 4 difs in 6 passes
