I am in a search for some parts for my 1945 Studebaker US6 that has a Hercules JXD engine 320 CID I need a head for it and also if anyone has some good pics of one of these engines in a truck that would help also since I know that I am missing some parts. I also have what I think is the complete Carter Carb with it.
Wecome to the site. Hercules is Jerry Biro, Google his name for contact info, he's got the mother lode of Herc gas engine parts. Good luck with the repairs.
Well I got ahold of Jerry and this guy is great. Was very helpful and had the parts I needed and then some. He also gave me some great pointers about this engine. Thanks again
I have a head for the jxd engine I bought a m45 that has a jxd hercules engine and the man who own it had the head work done valves, everything done to it ,i have the head gasket to, Send me your e-mail and i can send you pics send it to 59hd@bellsouth.net Thanks Clint
Clint Patterson this is what a WW2 JXD Hercules engine looks like it is a flat head no valves in the head. I do not know what a post war JXD looks like.
