I just put my motor together. I bought the car with bad heads and the motor torn down. I had never seen a supercoupe motor put together, but I took my time, read the book and took the advice of other SCCoA members and it started, idled, and ran perfect. plenty of boost and vacuum, and I got the timing right the first time. I just need to button up a few more things and it will be done. Maybe I just got lucky but I think that if you take your time these cars aren't as bad as some make them out to be.
