Its been a while since I've been on the site, been busy pulling a Detroit 8V-71N out of my 1973 Eagle Bus conversion. It was originally converted in 1997. I am installing a ISM 450 with an Allison 4000. I've got the new motor mounts built and starting to connect all the components. Thanks to all that gave me the advice to start this project. Are there any sites exclusive to bus owners to list my Detroit? I have a lot of spare parts to get rid of also. Filters, oil, etc. Thanks again. Will post pictures!
