Kurt mine is a 4.5 stroke so now you have me worried a little .It seems like the best road race pan on the stock stroke stuff, but I worry on the 4 inch stroke stuff.

So what modifications to this pan do you recommend ?ThanksThe windage at 4.0 is getting bad enough that GM would not use a wet sump pan, that is one of the drawbacks of the skirted design. If you are low rpm street driver it might be ok, but if racing is in your future I would use some type of dry sump with that stroke.

Been runnin one of those on my 416 for years. 7800 rpms all day long never had any issues here
Not minutes by any means since its a drag car. 9.80's in a 3200lb door carHow many minutes do you hold the engine at 7800rpm? What the heck are you doing!
I see pressure problems at 6500rpm under 1 minute with the larger stroke, the stoke stroke stays stable at 1 minute.

Its most likely going to Billy Briggsturbosb2, are you building the motor or is someone else?
Got it, I've noticed that you go back and forth a bit on parts, hopefully Billy will want to use what you have? Wouldn't it be a good idea to see what he thinks?Its most likely going to Billy Briggs
