I could never figure why G.M. listed the 55 at 180 and the 56 at 205. Might be advertising? The difference between 4 jet and wcfb is only .062 total. That would not make 25 HP difference. My late brother could never find a performance difference with the 2 carbs, if one carb was faster he would have used it. He used the wcfb on the 56 when he ran single 4. All the specs. i can find are identical. The only question is what the original head cc"s were.
cheers Jim
