New...or old topic. Who is making a low gear set (2.75 first) these days? Something that can live in drag racing, behind about 575'ish HP?

Pro trans ( was in Lancaster Ca now in TX) is the only place I know of that did low and high gear sets. I tried on years ago and my '60s slowed. 525ish hp 3,000lb with me , '66 Shelby .
