66 c10 lt4
LT4/8L90 into 1966 C10
Howdy folks ! My first visit so thanks in advance for your patience!
I bought a connect and cruise package that has engine , trans 8L90 8 speed (what a beast), ECU
and TCM . I have also a TCI chassis. Has anyone done this swap or anything I should know as far as firewall mods , most likely going to have to modify the tunnel
Any help would be appreciated!
