Notching Oil Pan for Stroker

#1 rod bolt is hitting the oil pan with no gasket and is just barely clears with the gasket.It's a 4" crank. It looks like I'm going to have to cut a piece out of the pan and have another welded on the outside...

Does anyone have any pics of there notched pans? Also how much clearance is recommended

Take a closer look at what it might be hitting because it's doubtful that the crank can hit the pan, just saying.

Has to be the windage tray. Did the same thing, spaced it off the main studs with 1 flat washer per stud. There are places to buy windage trays for bigger stroke cranks if you don't want to use washers.

Windage tray is spaced already. It is without a doubt the rod bolt on the #1 rod hitting the pan where the dimple is cast into the pan. .

It must depend on the rods or bolts that are used... some people have trouble and others dont

You could sand some material out of the dimple. It does seem to be hit or miss my Lunati crankshaft and Crower rods only hit the windage tray on #6 bolts.
