Jul 21st, 2025 | | | | Joined: Dec 2010 Posts: 253 Shop Shark | | Shop Shark Joined: Dec 2010 Posts: 253 | I am starting to mentally work out my engine swap and I need to use the bellhousing and flywheel from my 1945 truck. I have decided to convert the truck to 12 volts seeing as my 261 has all the pieces and is set up for it but I don't think the starter will mesh with the old ring gear if my research is right. Is there a 12 volt starter that will match up or can I get my 6 V starter rebuilt as a 12? Can the gear on my 261 12V starter be changed over to the 6V starter gear?
Anyone of you have installed a later model stovebolt into a 40's era bigbolt truck and can tell me about any other details I might need to know?
The good news is my water pump / fan looks like it will clear the radiator just as it is.

A 6V starter can be converted to 12V but still must use the 6V flywheel. | | | | | Joined: Dec 2010 Posts: 253 Shop Shark | | Shop Shark Joined: Dec 2010 Posts: 253 | The starter conversion to 12v maybe the way to go then. I have a 12 volt flywheel and clutch pack but I won't know until I take everything apart if the later flywheel and clutch pack will fit in the early bellhousing and if wiil except the early type throw out arm and throw out bearing.

I as well as countless others have done it for years and years with no ill effects.

No one said it was going to be easy
