Welcome to the Stovebolt communty!
I read your post in the VFD forum. Sounds like you already know a great deal about your truck and have a plan and end result established (noted in that post).
As a pointer or two in getting the most out our site, post your questions about specific tech topics you are seeking help with (like engine, drive line, etc.) in the individual forums in the The Shop Area
as those apply to your truck just like the regular trucks.
You should also think about posting questions related to your "Big Bolt" sized truck in the Big Bolts forum
as folks that spend most of their time in their probably have the best info that involves your size truck.
Looking forward to seeing more posts from you and we will do our best to try and help you out.
