Finished the flywheel today, ground the flywheel flat for the last time, made the conversion sleeve for the pilot bearing and pressed it in, and installed the starter gear from the spare 305 flywheel. There are some surface cracks but nothing cracked through, I'll be running it this way we'll see how it goes. Thinking it'll have plenty of life left.
Now onto the cylinder heads. Going to have to modify and install exhaust valve guides. I found valve guides from a Volvo Penta engine that will be usable for my conversion. These guides will be modified to accept good valve stem seals.
A 3 angle valve job is also on the list.
I'm also looking into a modification on the idler gear that will allow me to run the gear setup with the 305 timing cover, this will involve some machine work also. Some say it cannot be done but I'm not a believer yet...
