Longer transmission and moving mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So, did some searching, not finding what I was looking for. Anyway, I am swapping out the TH350 for the 4l80E. This is in a 1972 LWB Chevy 4x4. With the new transmission length, I need to make up around 4-1/2 inches. Was thinking of setting the transmission and transfer case mount back around 3 inches and moving the engine forward 1-1/2 inches. I'm sure someone has done this and has a recommended setup. I would like to gain a little bit of firewall room. Thanks
