Good morning, Three more questions as I move through the engine rebuild: 1) Is there any more complete on-line source for identifying casting/part no. than mymopar? I don't have a parts book from 1962. 2) I've looked at mymopar for exhaust manifold casting no. 2268253 but cannot find it - can anyone identify it? The mopar dealer doesn't know it either. 3) Are there any big block exhaust manifolds, other than something like the Max Wedge manifolds, that would have a 2 1/4 or better yet a 2 1/2" outlet. I thought there would be numerous 440 manifolds like that but I haven't found any. I have seen some manifolds that appear to have less restrictive flow lines, but they were also 2" outlet. I am a little surprised but I guess the 300H had 2" dia. manifold outlets, like all the other models - is that right? How about that higher horsepower H - did it have larger manifolds? Thanks for your help. Carlton.
