This is my 66 Bonneville. Replaced engine with 400 from 68 Firebird (cracked block in 455..389 was in it originally before I had it.) What I meant about "tightning up" transmission is replacing seals and gaskets, did not rebuild it shifts very well and does not slip. I love to drive it around town. It is not a show car or even close to one but I really enjoy it. Fond memories of my parents 63 Catalina. Will try to do better with camera shaking next time haha.
