I'm in the process of doing an engine rebuild. Got a Ripp's SC kit, forged pistons and rods, Texas Speed blower cam, stall converter, headers and full exhaust. How much horsepower can a stock drivetrain handle? Thanks!

The zf 8 speed from the srt is only rated to handle around 550-600hp. That is one thing people take note of. Your axles would probably need replacing depending on how nuts you go. Also, rear upper control arms since the factory ones are the shitty ones used in V6 models.

this is what the manufacturer rates the HP70 at.
everyone’s driving habits will dictate how long the trans will last.
had this same discussion with another forum member and this is what he gave me.
an HP95 will not fit in an SRT without heavy modification in case you thought about that.
