Any reason you didnt use the crank scraper on the new
unit?

Art, I have run dynomax ultra flow welded on my 70 challenger and picked up HP versus the headers.

They are street legal 3 inch inside pipe and come in oval and round. Part # 17220 Oval, 17223 round center in and out. Assuming you have a collector with a 3 inch piece on you can build your bolt on kit with adj length and turndown from Jegs for cheap and easy. True straight through and they flow like none other.

For your data file if you ever do the muffler thing again, or decide to drive you Super Stocker to the track!

I did extensive dyno testing with crank wiping scrapers,not one increased horsepower,not used in cup racing or pro stock,,the best oilpan is NO oilpan

On the first motor I had a 4 quart oil pan. So I wanted to do everything possible to keep oil around the pickup.
On the new motor I have a 6 quart pan. So I just put in a windage tray.
