. No 1320 runs yet. Weight with me should be around 4100.Nice, do you know the race weight or have 1/4 mile times?
10R80 is amazing for 60-130 accel. My 3.15’s and 28” tire kills my 60-130 after the shift to 3rd......My best so far on E45 has been a 5.06. Out of the box beefcake special vortech with 10r80, I'm running it pretty conservative at 16.5* timing. My race weight was 4020 pounds.
I’m THIS close to doing a 3.55 rear.........Yes I agree it works very well. I was surprised by the results. I had a 6r80 3.15 car so I know what you mean.
