There are alot of builders that guarantee the strength the problem is the cost. That's why I went th350.

 

Tanners t-56 has been completely gone thru. Cyrogenically treated parts and every high strength option available. Not stock.

 

Ya, I was gonna say.....it's not like that thing is getting baby'd going down the track....

 

the stock trans did propel me to 10.14 @ 135, that was complete stock internals. still mostly stock internals, except for viper 3/4 fork, output shaft, carbon fiber synchros, like i said it is still pretty much bone stock
