Im Planning on building A 4AGE Twin Cam For my AE86 Corolla. I found the car for $400.00 with the engine needing to be rebuilt and I know a lot about engine but never got inside one before. I think this would be a challenge i would be up for. Im not worried about tools i have someone with a shop that has tools. Can someone point me in the right direction as what kind of books/Service Manual I need.
