Installing a 5 speed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello everyone, I'm looking for pros & cons on installing a 91 1/2 ton 5 speed into my 67 1/2 ton. I'm putting a 400smblk with dart pro 1 heads and a few perf. parts in the truck and don't really know how much abuse the trans. might take. It's a nv3500 and don't know it's torque rating. I know everything will bolt in and I'll need a 400 flywheel but was unsure about cutting a hole in the floor (new carpet) and the trans not holding up. Any info would be appreciated
