I have an AQ271C with a DP290 drive in a Cruisers Rogue 2420. I would like to up the power a bit, however can not find anything on the torque/rpm limit of the drive other than the factory RPM limits. my goal is to go from 270hp to about 350hp with a 383 stroker (keeping with a SBC)

does anyone know the limits of this drive prior to things breaking?

With 350 hp, you won't even make that drive sweat.

I've never heard of a limit, but with a 350 block, you aren't going to have problems. They run 6 cylinder diesels on that type drive. you aren't going to get that kind of torque out of any 350 block.
