What did you buy as far as a retard box goes?Running the Edelbrock RPM, the plugs were a little wet. Running 82 in frount and 79 in back. I started out with 950lb of nitrous so next time I think I will leave the jets and run 1000 to 1050lb and I won't have as much flame out the headers. Order the retard box today and will have the trans brake in for the 21. If I remember to turn every thing on it might run.
