ive only made 3 passes in mine. at the time it had about 135k on the stock motor. only mods was a loudmouth and k&n cai. street tires at 18 psi, launch at 1500 rpm, shitty 2.30ish 60ft but still pulled a decent 13.9 @102. i was happy with that time.

I know what you mean about the peak torque. Driving both an LT1 and LS1 there is a huge difference in feel and throttle response. Almost as though the LS1 feels lazy down low compared to the LT1.
The LT1 is much more of a tire spinner in first gear. I find the stock LS1's are very easy to get moving with minimal spin.
I believe it has alot to do with a moderate size cylinder head on the LT1 promoting good throttle response and torque,,,only 170cc intake runners.
Where as the LS1 is slightly smaller in cubic inch,,,,yet the cylinder head intake runner is 200cc,,,rather large for such a small motor,,,makes them feel a little soft down low in my opinion.

Yeah soft down low, then they scream up top!

Nothing wrong with LT1's at all. I've owned enough of them. Just hard to compare them performance wise to an LS1.
You're talking 23 degree heads verses 15 degree heads,,,,,the power potential between the 2 are night and day.
