I recall the low end of a TPI and LT1 being nearly identical, yet everyone seems to think the TPI is superior there. I'm not convinced.
The long tube TPI is superior in off-idle torque than the LT-1..... it'll make literally 40 more ftlbs down at 2500-3000 rpm...... but it sacrifices to much rpm to do it..... hence the LT-1 is drastically superior to the TPI long tube runner set-ups in my opinion.
For stock motors, the actual peaks are probably similar at close to 350 or whatever, but they occur 1000 rpm apart.
The Superram is a different animal though, it'll give you an extra 500-1000 rpm over the stock TPI....and yet only give away a little torque off-idle, but makes up for it and then some by 4000 rpm.
