Not to start a flame war but. You apparently just haven't raced a simular LS1 set up. I've raced lots of LT1s way faster than me but they always have had way more mods.
LT1 with = mods and = weight not beating my car.

 

My main reason in asking the original question was to get an idea of whether the '96 needs to be checked out........once you drive something faster for a while, whatever you had before will seem slow, or so I've found. From the responses I have gotten, I think I will, in fact, have the car scanned. I did find out that the '96 had been fed 87 octane gas for the last few tanks, and as I remember, my '95 I had a couple of years ago didn't like the cheap stuff at all......maybe that is the main problem, but then the gas issue seems to be arguable around here too.....maybe I'll take'em both to the track soon & compare.

Thanks for the responses everyone,

Jeff

 

Look at the horsepower ratings of those cars. They are way higher then stock.

 

Wow, that's gotta be the most inaccurate "Top 50" ever! Maybe it was accurate in '97, but I'm afraid that now the topper might be the '04 Z06 with an 11.97 @ 118 (unless the Viper is faster now too? ) and if a '96 LT1 could pull off a 13.4 @ 106, then by gosh, LS1's should be good for high 12's @ 110+!?

......oh, and I don't believe #6 ('97 Hurst/Firebird) doing 12.99 @ 103 mph!? Sorry, but I doubt it. A car doing ~103 mph is only good for mid 13's at best. Look at every other car on that chart even!

 

Not trying to add fuel to the flame, but there are plenty of H/C LT1s quicker than your car. Not trying to discredit your times, your car runs well.

 

Actually the '96 SS was not 270HP. It was rated at 305, and 315 with the optional 2OTL exhaust. The ratings for the '96 SS are correct, as are the '97 LT4 SS which were rated at 330hp.

 

Nick, the heads I have on my car are junk 5.3 heads. I actually lost 1rwhp from my stock LS1 heads.

Let the winter mods begin.

 

I didn't know that, sorry Al

 

The crank numbers looked about right to me??

as said..they listed their sources....

Evan Smith has driven muiltple stock LS1 cars to high 12s stock.. maybe you guys just suck at driving.

 

Never said it was a current list, in fact most newer list dont have the LT1 stuff on them. Thus I provided this link solely to show you the LT1 times. You guys are never happy...

Umm.. Muscle Mustangs and Fast Fords has done that a few times. Though the traps were less than 110

Why not? Mustangs do it all the time??? BTW..the hurst was done by LPE I believe

"In 1997, the Lingenfelter Hurst Firebird was available. Lingenfelter took a black Firebird Formula with the WS6 Ram Air package and added a 58mm throttle body, LPE intake manifold, LPE CNC ported LT4 heads with hardened pushrods and guideplates, Competition Cams 1.6:1 roller rocker arms and heavy duty dual valve springs with titanium retainers, aluminum driveshaft, Hurst shifter, shorty headers and Borla cat-back exhaust. Power was set at 350 HP."

You guys know they made F-Bodys before 1998 right?

 

When I test drove my first LS1 car, I wasn't impressed at all. At the time, I had my '95 Z28 a4 and the car I was test driving was a '99 Firebird Formula a4. The LS1 didn't "feel" slower than either of my LT1's, but it didn't feel any faster, either. Now, the LS1 did feel significantly smoother than my LT1's, and I probably would have bought the bird but they wouldn't budge on the price. Fast forward a year to when I test drove a red '98 Z28. Same result. It didn't feel slower than the LT1, but it didn't feel faster, either. However, on the way back to the dealership, I took the highway instead of the side streets. I got on it a couple of times around 60-65 mph and finally understood what all of the fuss over the LS1 was about. It screamed from 60-100 in what seemed like less than 1/2 the time it took my LT1. That's where you'll feel the difference between the two. I ended up buying that car...

 

Excellent post eles1, 100% accurate

 

Only innacurate time I see there is that 96 LT1...no way in he!!...it was probably a LS1 and whoever tested it didnt know the difference...obviously the list is outdated

 

315 with the 2otl . are u sure , where did u get that rating, i alway thought that 305hp was with the 2otl??
thanks
bobby

Guess1
yes 87 octane could be ur main reason y the car does not feel like it should, LT1s dont like any fuel under 93 octane,
anything less than 93 will cause detonation and pinging , ur knock sensor will pick that up and retard the timeing , which wil result in a loss of power,
anybody correct me of im wrong , thanks

 

As I said lighter cars with, more gear, more tire, and much more than my little stage 1 heads. Like I posted above equal mods. Equal meaning the same not just simular.
