72 GMC - Engine hitting firewall...need advice - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I took the 350 out and I'm installing a 383 stroker. (We're talking about a 72 GMC 3/4T 4x4.) We finally got the engine built and installed, but it's barely touching the firewall. What should I do? It's the first time I've done this, and I'm not sure what the best option is. Should I move the firewall back? notch it out? move the engine forward and the tranny too? .... advice and pics of what to do would be very much appreciated. Hope you guys have a great x-mas.
