finally ordered there converter looking to pick a tenth or so. Have heard nothing but good things about there product should have it in a couple weeks
Can't wait
 
Just got my 727 back together with the new cooler /with fan and the 4200 dynamic converter , man a properly tuned 727 is one bad transmission
the converter feels great / back to the track as soon as I can
I think this converter actually dropped the cruise rpm about 100 or so rpm
So far very happy but the 60 ft times will tell all
thanks and will report the results
 
keep us posted

my 3800 lowered my cruise rpm by 300 or so compared to the mopar 175k I was running before that
 
This is the result from the dynamic converter
Went to the local track Sat
Pretty happy with the dynamic guys and there product
Before. 12.63. After 12.32

Congratulations! That's fantastic. Gains across the board, except trap speed......Probably just differences in conditions as far as that goes. Well done. :thumleft:
 
Are you talking about Frank Lupo dynamic converters? He has built converters for me for a long time. Can't say enough good about him.
