1989 b2200 straight 6 swap

Well, 1 year and 10k miles have past since I bought my truck. Its my first vehicle and I want to keep it forever. But, like all of us agree, 86 horses sucks. Today I scored a 258 Jeep for $150! Only 30k on the rebuilt bottom end, a bigger cam and gm hei distributor, supposedly makes around 200 horsepower, and a shit ton of torque. The head needs a valve job, and I an going to do a little port matching and polishing. Its quite the odd choice, but it was cheap and different. Plans are ax15 5 speed, and a Toyota rear axle with lsd. Its going to be a while before the build actually starts, as I need to sell my Suburban to get the cash to do the project. I wanted to post this to get feedback, tips, and just see what everyone thinks.
