I have seen on 428 that was crossbolted like a 427 and it also had
oil lines spraying
oil through the side. I know the guy that had it built spend thousands of dollars setting it up for drag racing. Never heard it run but the builder told me it would be as strong as a side oiler.
My thoughts are that it might be cheaper to buy a side oiler than to modify a 428. My personal opinion is that the 428 is a very strong engine and I believe it was every bit as powerful and dependable as my 427 (I put 4000 race miles on mine and it would be here today if I had done a routine bearing check each year).
