408 stroker oil pan windage tray I found out today that a stock windage tray will not fit on my 408. Who makes a windage tray for 4" stroke applications and will my stock truck pan clear or do I need to purchase an aftermarket pan?

We definitely recommend buying a 4" stroke windage tray instead of modifying the factory one.
To make the factory one work, you need to space it down with washers. Since the pickup tube bolts to the windage tray, the pickup tube will not be too close to the bottom of the pan, which can cause oil starvation. So you have to bend the pickup tube bracket to try and get it back up to the correct position, which is very difficult to measure. Not to mention the windage tray doesn't perform as well with spacers.
We make aluminum windage trays that are completely bolt-on for just about every LS oil pan setup. Clears any 4" stroke without any second guessing. They are made from aluminum and lighter than the factory windage tray as well. Dyno tests have shown that are windage tray will gain ~15 WHP over running no windage tray at all, so definitely run a windage tray.
