Rear end advice for racing with a 4 speed

I agree I have a Dana 60 shortened up 456 gears and spool for whenever I decided to build my race car, I have a moser 83/4” just a braced housing I’ve been wanting to build but can’t find cheap deals for a center section. My street car has a 8.8 under now, I shorten/built myself so cheap it’s a no brainer for me.
