K20s only came with high hump, so your 67 cab will need that to clear the TH350 that is also likely in your K20. As for clearing a 4L80E, someone else that has done that swap will need to chime in. Note that BBC never came in Ks, so not sure what other things you might run into, but there is sufficient space - many have done it. Usually happens as a C20 with a 402 being swapped onto a K frame, motor coming along for the ride, so you shouldn't have too many problems. Need to make sure the tunnel space is sorted out - I'm assuming a high hump will be sufficient. You have a high hump if it's bolted in. If not bolted, it's likely a low, and that is what I'm expecting for your 67 cab.
