Does anyone have any idea what hp or torque a Richmond 4-speed can handle? Like the ones you can buy from summit or jegs. I can't seem to get a response from anyone on this.
Go here http://www.richmondgear.com/01fourspeed.html and click on 'download PDF'. The PDF file contains specs on the transmissions including torque ratings.
most manual transmissions can easily exceed their factory ratings,ie the t-56 is rated for like 440ft lbs but can handle way more. if i remember lots of t-5 were rated at 295-300tq and the 5.0 mustang had 300tq stock
