I have had the Moroso oil pan for 2 years, I am very happy with it, it's a very trick piece, nice welds, it's baffled, so when you accelerate the oil flows back towards the pickup, then if you hit the brakes, the trap door shuts and keeps the oil at the pickup. Installation was a bit tricky, you will have to grind the girdle (type r only) support brace to make the pan fit. The secret is to run less than the pan capacity to reduce windage. Don't tell anyone!! And the price is not $400. It's more like $350 or less, make sure you talk the salesman into throwing in the oil pickup and the mounting stud kit. The only problem so far is my Z10 radius arm kit comes damn close to touching the pan, I will post if there are further problems with this issue.
