Update: With almost 24000 miles on the truck since the EFI conversion the truck is still running great. I have no idea how many total miles are on the engine but it runs fine and doesn't smoke at all, however it does have a significant oil leak and I have been searching for a 261 to put in it for some time. I finally found one last week about 10 blocks from my house. I dropped the engine off at the machine shop on Monday to see if it is rebuildable. If so I plan to chronicle the install of it and my Mculloch supercharger on this site. Plans are for a performance rebuild with a blower friendly cam. My friend Greg is working on a fueling strategy for the new blown engine. Hope to have something to report shortly.
