We all love project threads here... Especially when they are kept up to day with pictures. I have a 1989 prostar which will be an identical power train set up as yours with perhaps the exception of the transmission. (you will either have a 1:1 or the 1.5 :1 powerslot. Motor will be a 351 Ford. Im sure you know these basic things. We all love to help out as much as possible so please ask away. A lot of the more senior members are a wealth of information and have done most things at least twice.
Good luck; keep us up to date.
