I guess my old dog is in the "freak category".. first did 377/376 on Chuck's old tune.. Then after NEVER being able to get the freakin po300(random multiple misfire) code to come off, I took the car back to HPE when Owen started doing tune's over there.. results were insane! The car was currently so lean across the board that that's what was throwing the po300. basically in the neighborhood of 14.5:1 a/f at 28 deg. timing at WOT if I remember correctly.. not to say chuck cant tune, cuz Iv seen some pretty wicked cars that hes tuned.. I dont know what was going on with mine.. anyways, owen tore down the whole tune and rebuilt the whole fuel curve and changed some timing tables, and basically kept the overall 28 deg. total timing and just added alot more fuel..

375/397
Iv also got a dyno sheet from a mustang dyno at Turbochargers.com here in houston showing 381/404

with the acception of having 1.8 crane golds in at that time..
whats really crazy is that I used to have the original ls1 that came with the car and had all the same bolt ons with the older version trex cam and only made 396/377 with a much shittier power curve and this ls1 is out of my buddys vette that did 305hp stock with a paper air filter before he yanked it to have MTI build a 427 for him. Thankfully he yanked it right around the time my original motor blew and I got the longblock! This thing stock is leaps and bounds faster then my old one with the trex cam. My buddy Kenny in his fox has raced both setups and he can attest how much faster this one is. GM's got some beer drinkin/hottroddin automotive machinists in there getting a kick out of trying to hide uncertain parts into uncertain vehicles! lol

Mods list when dyno:
01' vette ls1 with UNPORTED "241 heads" Could possible have the ls6 cam tho, think the later vettes got them slipped in when noones looking. but not sure, Iv never taken it out of the motor to mic it.

Ls6 intake
slp lid/bellows
free ram air mod
pacesetter LT's
Pacesetter ORY
manaflow 3in. exhuast(no cats)
6speedinc. m6
ls7 clutch
Ls7 flywheel
stock 3.42's
and no a/c belt..

had crane gold 1.8 rockers,ls6 yellow springs, and comp stock length pushrods in it on the mustang dyno run. I figured Id lose alot of power on it.. boy was I wrong!
