Default 73 Shovelhead

I inherited a 1973 Shovel from my best friend when he died. He was suffering from dementia when he passed so a lot of the parts are just in bins and others missiing. Can anyone tell me where I can find the plate/pan that goes on the bottom of the engine? He had covered it with masking tape and then painted it. Got loads of questions but thought I would start simple and work my way up.

Can you take a picture further back? That's not the bottom of a shovelhead engine.

Not from the bottom, the floor is in the way, LOL. This is the number stamped on the casing just in front of the forward jug.

Delkron trapdoor aftermarket cases looks to me, good luck hunting one up. Get busy on google, ebay and maybe contact DragonMan's in Colorado Springs, Mel used to do a lot of rework on seconds of those for resale, look for his Machining stuff.
Somewhere on the motor is a brand name cast in, find that.


Oh and have a mod move this to the Shovelhead section, lots more people will see it that could help, here.

Good news they plan on resurrecting the line and may have both cases and parts by this fall. Thanks to everyone who took the time to help it is greatly appreciated. Now on to another fun adventure in fixing the 1973 Frankenstein.

Delkron used an o-ring instead of a gasket that never sealed 100%. Run you serial number by Delkron to determine when those cases were made, ebay and several other places have old stock trapdoors but you need to know what year your is, there's pre 86 dates & post 86 I still see post 86 doors for sale still.

Another option, any small machine shop can make one for you. Isn't complicated, just needs dimensions and accurate hole pattern spacing, just use a sealer as a gasket. What we did to seal the damned things anyway.
