Anyone had these symptoms with a 904?

yeah when it comes to 904s, mine have accepted a lot of cobbleing over the years. I reconditioned my first one in 76,on the dining room table,in an apartment, that my new bride and I had just moved into. It was a core, a spare, and I didn't need it until several years later. It is still with me, having outlived several A-bodies.
Ya know and that's another thing; that trans was out of a 71 Demon 318, and was the best shifting trans I had ever had. I built a couple of clones, and I think I still have one or two of those in the back shed. 1971 was a good year for 904s
