Hi, I’m new to the group. I’m Emory D.Shriver. I go by my middle name (Dave). I have a 67 Firebird 400 coupe that I purchased in September 2022. It has a 1973 block bored to 406 making 410hp with a TH400 transmission. It has positive- trac rear end, (not sure what ratio yet). I had a 68 Firebird coupe that I bought for $700 when I was 16 in 1979. It was rough, I had bought 2 68 parts cars to keep the 1st one going. Those were the days!
