I considered 301 manifolds as well and the passenger side would work well. The problem on the F-body is where to run the downpipe on the drivers side. 455turbo routed his around the steering shaft and was obviously not an easy task. I'm sure he realizes the problem in this area. My car, however, is a 4-speed and the Z bar prevents this routing. The only ideal route I could see other than modifying the firewall was between the #5 and #7 cylinders by snaking the #7 exhaust tube to make room for it as noted in the above pic. The only other option is a very long pipe that crosses under the frame rail at some point which is unacceptable to me. A 301 manifold or any other for that matter would block this passage way.
I have 2 T-3's from Regal T-types which I'll probably use. I do have 1 turbo from a 301 car and if I can find another I will use them. In fact if anyone on the board has a decent one lying around I may be interested in swapping for Poncho parts or possibly purchasing.
