Hey guys, just installed a new 10" converter in place of a restalled d5. The car was trapping high 109's and yesterday with the 10" it slowed down 4 mph. Shifting at 5500 out of first and 5200 out of second. Rpm drop was 500 between shifts.
Engine is a stock long block with stock valve springs and my question is with the engine staying between 4700-5200 most of the run could this be a valve spring issue or do I need the converter tighter? Thanks for any input.
