I am switching to a 4 speed too, but I don't know if this will work with the 4 speed setup. He was running a floor shift auto, with a non column shift steering column. It looked really nice, and there was probably 1 1/2" clearance between the master cylinder, and manifold. To answer your question, all he said was b body manifolds, i don't think there is alot of difference in the b body manifolds. Sorry I didn't get pic's but I put the wrong card in my camera, must have been in a hurry! I am hoping to see him at another show this fall.
