Hi guys, im new to the site and was wondering if i could get some advice on a new trans for my 84 2wd 1/2 ton gmc on 31's. Its got a new 350 crate thats about to be pushin about 450hp. I currently have a muncie 3 speed (was on the column, but now on the floor). I am having trouble with putting the power to the ground. I have been looking into a new 5 or 6 speed to put into it for a while now. Id like to have a quick truck on the street, but able to pull a descent size trailer every once in a while. I saw that tremec makes a 5 speed kit for around $3400, but read some threads about it not holding up to the weight of a full size truck. Would like to go all out with a 6 speed. Any help with what i should go with would be greatly appreciated. Thanks for your help.
Dave
