What's worse are all the people who say "check the sig", because they're too damn lazy to copy and paste their signature into their post. This way, when they get a different car or change their signature the numbers and mods are no longer listed in their sig and you're left with no clue as to what power they made, what numbers they ran or what mods they had. That's happened about 10 times in this thread.

I have 3.42 gears, 2800 vig stall, asp underdrive, 30 svos, jet tuning, magnaflo catback, 52mm bbk tb,CAI,
have CC305,1.6 rockers,Mac mids,no cat and as said my head choices are LE2 or AFR 180 elminators. So anyone got something close to this? Wondering if can hit 360 rwhp with the above mods.

1994 trans am lt1 M6
MODS:totally stock...it is pretty much bad *** lol. mods will come soon. I see all of these numbers on here and I was wondering how much rwhp an lt1 fbody has to begin with. I know what it is at the crank....but in order to see the gains I was hoping you guys could enlighten me. I do at least have newer rims on my car(my one mod), that has gotta be at least another 15-17 ponies lol...oh, i forgot, that only works for ricers.

I dynoed out at 313hp and 315ft. Had a ignition stumble after 4800 that I think affected the over all numbers but I think it's with in 10hp? We only ran the car to 5700 so i don't know what it could of been but it's a start.

The computer hasn't been done yet but I'm not gonna do it until next winter when I put the heads on it. Any guesses what a computer tune would do.
