Need recommendation on drag radial

[BILL-C]

I have a street / strip el camino with 496 BBC, TH 400,4.10 rear gear. Last pass at dragstrip was 11.14 @ 125.5 mph. I finished off my M/T ET STREET 275/60-15. 6 years old, 65 passes and a bunch of street miles. What is best drag radial for this application?

MT should have a crossover for the drag radial size wise. Set up is something else. Tire pressure will have to go up. I think we were running 12.0psi with bias ply, ended up around 15.5psi with drag radials. The other thing is they don't grow much so you rpm will go up at the end of the quarter I think we went from 7000 to 7300 with the same rollout tire. Tires really seem to do their thing in the 1/8th mile noticeable gains at the 330'.
