The Website you posted HANLONMOTORSPORTS.COM claims
"HOME OF THE FASTEST TREMEC EQUIPPED 5.0" @9:15/152mph
while the one at X2CMOTORSPORTS.COM claims
"HOME OF THE 8 SECOND TREMEC EQUIPPED STREET DRIVEN MUSTANGS"
Im sure one is no better than the other. I can say the X2C tranny is all brand new and not rebuilt. It sound like HANLON rebuilds them. I guess it really comes down to is price and how well they back their product.
do you know what he asks(Hanlon) for one of his units?
