Valve train noise
I just did some research and found out that the big block pushrods push on an angle up to the rockers. I never knew that. Looks like about 3/8 of an inch offset. This would push the rocker side to side. The small blocks don't have that problem from what I see. They are perfectly straight. The small block would not have that problem. I don't think that the side play will be that critical compared to the big block setup. Someone correct me if I am wrong.
