6L80E LS3 Swap in 65 C10? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can anybody tell me if it's possible to swap a LS3 with a six speed 6L80e trans into 65 C10 without cutting up the floor pan with a low hump?

In my 70 wth a low hump I had to stretch it. By pushing up on the center of the hump with a big pipe and floor jack, and then used a dead blow hammer to bump the sides in to make a hump with a curve. I gained about 1" pretty fast and also bent the flange lip up.
