Default Does anyone have a LT1 vs Ls1 graph

Would like to compare them, searched google and these boards a bit but couldn't find anything.

Go to this link and go all the way to the bottom. I do not know how to make the image show up in the post. Both were dyno'd on the same dyno on the same day.

96 Trans Am ws6- 6spd Jet Hot Lt's, 1.7RR's and a mail order tune.

00 SS- 6spd Jet Hot Lt's, Lid, and dyno tuned

Don't have a link, but I dynoed along with a few LT1's and and mod for mod the LT1's were pretty close on the low end torque (2500 - 3000 RPMs)but fell after that.....not close on the HP.

I think that this is where the discussion on LT1's having great low end tq comes from; because, if you think about it, it's almost matching low end tq while not being as powerful (no offense meant).

Haha very politically correct.

It really doesn't matter once you start modding but it does seem that an LT1 has better low end torque charactoristics while the modded LS1 SCREAMS up top. I've modded both and they are both great motors.
