Well Grigg once again you have told me something I need to think about. I have a 300 GMC that I really wanted to do this to in the beginning. I knew the 6bt requires a lot of cutting the firewall. I honestly have not bought the truck with the 453T but it has a 5 speed and 2 speed rear. Guestion is how would you mount the radiator in the GMC with the grill supports in the way. That is the only reason I have not already built this truck. I plan to run this truck on the interstate and in town. I really like 10 speed idea but the allison is also a great idea for the city where I will use this truck most. I have to do some serious thinking about this.
Thanks
Brad
