My 68 camaro came with a m20 muncie trans 4 speed. I’ve read that they were only rated for around 450 hp. Well im going to be running 538 gearing in a dana 60 rear with a four link set up. 32x17x15 tires 700+ hp looking for recommendations for a trans that will fit my needs. Any help would be appreciated.

Magnum 6-Speed Rear-Wheel Drive Manual Transmission

 

Ya, what Y2 said. That would be my choice as well.
