I'm thinkin of doin a 6.2 swap in my 86 k5. The plan is to try and find a complete truck and just swap everything over. From my research here it seems I would want one w/ a serp. belt setup with a J engine code. I guess that means no emissions. I'm not looking for a monster, I just want something w/ better fuel economy and power than my stock 305. This truck is my DD as well as weekend wheeler. I do everything from mud to sand to trails and mild rocks. I've got a few questions: Should I even attempt this? I've never done a motor swap before but I feel that with plenty of good info I can do it. I gather that the 6.2 should drop right in to the motor mounts. Is this correct? Will it bolt up to my 700R4/np208? Will this tranny even hold it? Do i need to move the tranny at all? How do yall like runin the 6.2 NA? Does it build enough tourqe for you? What are some real world numbers for this engine as far as hp/tq/mpg? I found this over at fourwheeler.com. http://fourwheeler.com/projectbuild/p52095_image_large.jpg They did a banks turbo on a 6.2 in a k5.
