Just wanted to see how safe the stock trans is running mid to low 11's. Have you heard of people running them for very long running 11's? I just don't want to destroy the one i have if it's not possible to run 11's without it taken a crap. I'm just about to install a PTC 2800 converter and i don't want to waste my time if you think it could damage the converter if the trans craps out. Thanks
