Car was running as of this morning! Mechanic still has it but had me take it for a spin.
We are all very disappointed in the performance - and think it is the strangely behaving Monster Transmissions 200-4R. It is upshifting quickly, not kicking down... not getting a good punch. Feels like a 200hp car but the engine seems solid. TV cable can't get tighter. Earlier in this saga, there were problems with my first Monster 200-4R, which they eventually replaced. This is behaving similarly.
My car, even with the engine having torn all bearings through the copper, felt strong and like it wanted to 'go' with the THM400. I wanted overdrive (I do lots of highway, and even with a 3.08, 75mph = 3000rpm = heat = wear & tear = gas = etc)... the deeper 1st and 2nd gears were also desirable.
We are having a local transmission expert check it out this week. He will either be able to modify the config or suggest I go back to the THM400 and just deal with the RPMs. Much as I do not trust the machine shop that had the engine before Ken, I have limited faith in Monster at this time.
Also getting a lot of tapping noise from the new roller rockers. Not sure if they are making contact or loose. Chatting with Ken Keefer tomorrow.
