116 trap with 4000 lbs is 481 hp using standardized 1/4 mile calculations. 850 crank hp should be low 10s with traction, but even without traction the trap should be minimum high 120s, low 130s in the trap. WTF did they do to this car to make it so slow? 0-60 and ET in the 1/4 mile are traction affairs, trap is where…

No on both counts, having owned a 335 and done the work on it, it takes time but never had to pull the motor for anything related to the turbos. No idea why you would need to pull a motor to do a gasket on an inline 6 either.
