Sent my Borg Warner Super T-10 4spd to a local old timer named "Merv" who does racing transmissions in the area. Ive had the thing for at least 10 yrs and never used it. I knew it was very good but i had him look it over, replace the front and rear seals and remove the vent/breather off the top of it and tap and thread in a barbed fitting so I can vent it to a little K&N breather up on the firewall or to a puke tank. I know from experience if you dont do this when you run them hard oil will come out of the vent run down the side of the trans and make smoke, bad smells and run the trans low on oil ....not good.
I asked David about the the strength of the T-10 he said he ran one with a cooler in his old Busch car that made 736hp for two full seasons before it finally let go. Eventually I will step up to a Jerico clutch less "dogbox" tranny but this will be good for now.
Oh the old timer said the trans was "in real good shape" and "is good to go now". Charged me $200
