Not exactly.
I said advantange to the SVT in 1st.
Even in 2nd. (only because the SHO is taller geared, the SVT accelerates faster)
Advantage in 3rd to the SHO because it has a stronger powerband then the smaller 2.5L engine.
Since you will be in 3rd gear roughly half the 1/4 mile this is why the SHO wins.
If it were a road race the SVT would rip up on the SHO because of better gearing and far superior handling. It's a straight line race though. Advantage to the bigger engine.
As for my old 2.5L engine. It whooped up on SHO's. Then again it wasn't stock either.
