OP, do you have a video of your pass? If so, post it. I'd like to hear your driving skills before making an assumption.
One key fact a lot of people tend to forget when arguing MPH is how fast you shift. I've jumped in peoples' car before that was going slower than it should, and picked up 4-5mph based on better driving/shifting alone. I'm also typically bigger than most of those people (235lbs) so I added weight at the same time.
I'm not saying this is the case with the OP's car, but it is something to think about. A car capable of 135+ traps can be brought down significantly lower with 4 slow shifts.

Looks/sounds good. Did you notice a lot of difference in the tone of the car when you went from the 224 cam to the new cam and heads?
Cause it sounds more bad *** now than I remember from the last 224 cam vid.

My car dyno's 451 rwhp and traps 127mph in about 1000 da. weight is 3200lbs in a camaro.
I would think that with yours being about 300lbs lighter and maybe slightly more areodynamic 130mph would be expected with 450rwhp....ish
But also mine is a 4l60e car with a 3600 unlocked converter and you are 6 speed...

wow! my LTx junk is about spot on with your weight, power and unlocked 3600 stall. I go 126mph and some change myself.
I think the OP car runs hard and being light weight would be in the 450 area as many have stated.

To bad you did not come to the dyno day at Turbo Tech in Tacoma. I did not even realize your from Washington state. We did have a RX7 with a stock Ls1 that put down 286 (I believe).

I know who that guy is... he's definitely having some tune issues. I didn't hear anything about the dyno day; would have been fun to put my car on. I'm quite sure my car will, as many of you guys have said, put down 450-460whp...

Well whatever power I'm making... I finally made 10's by running a 10.990 two nights ago! It really sucks that some track personal decided to start up a little tractor right as I was about to launch 
. oh well, my car covers up the sound pretty well!

Say hello at LSX Nation.net North West Section. We mostly migrated over there for forums chat only. Post your times in the time section also... They would be happy to get a new LS1 on board. You'll find that this is where all the fast LSX/LTX are at in the North West...
