Some things will never change, right? There are designs that never need to be improved, updated, or modernized, right? Wrong. The guys and girls at Moroso have proven this with the redesign of their core style stroker oil pans for small block Chevrolet engines. The design changes come in a couple of faces, the biggest being the elimination of some bolt holes to attach the pan to the block. Here’s why they did it.
Instead of having customers order 100% fabricated oil pans, Moroso offers “core” pans that they modify. They get the cores in, add the sumps and other elements and then ship them. This is a way to get you the right oil pan without breaking the bank. They updated their cores recently be incorporating some of the race technology they have developed over the years. The firs thing was the addition of the stroker notches into the pan to give you the clearance you need for the increased stroke of the engine. The second thing they did was change the form of the pan so that a full length windage tray could be added to it, not just the partial one as in years past. Thirdly, they removed some of the bolt holes in areas where the block is most heavily notched and the corresponding notches in the pan are. Why?
Well the oil pan is never filled to the top (at least it should not be) in the car so there will be no leaking or weeping if you have properly installed it in the first place. The clamping force of the existing bolts is more than sufficient to keep things happy and sealed.
This is a cool video that shows even the most tried and true products and designs can be improved and built upon. Good for Moroso. If you are building a stroker, this pan could be your jam!
