1970 "DUPED" Dart Swinger

I did a bit more work to the engine today. Sand blasted a lot of the bolts, got the engine on TDC #1 and stuck the Mopar distributor in that I had in my 340 Demon.

I did figure out the issue with the dip stick... Due to this having a stroker crank in it the builder shimmed the windage tray down with stacks of washers to clear the crank. Doing this caused the dip stick "when slid into the tube" to actually go inside the windage tray where I believe it met a spinning crank shaft and met it's end.

That's a lot of sealer. For my own info, is it necessary? I smeared a little around the coolant holes and that was it. Hoping it will suffice??
