I read this post and I almost laughed. You still have 16 leaks at the lifters on a SBC. That still adds to the oil volume requirement of the engine. And still it will oil to 10k plus. STOCK.
You are still feeding 16 pushrods and rockers and it will still oil to 10k. Stock.
It's getting the oil to the mains on time. The Chrysler doesn't do that and the crossover doesn't fix that.
We are getting ready to do an R block with W5 heads. If I feel like it, I'll make a video of how to make on oil without the crossover and none of the other feed lines.
Or maybe I won't and I'll keep letting people waste their time and money on that modification.
BTW, I have never read where Bob Glidden said he used the crossover. I've read other people say he did, but never him.
On top of that, he was still a mortal man. He wasn't perfect. I doubt he used one. And if he did, he knew it wasn't for slowing down oil velocity. That's preposterous.
