Will the 420a bottom end and stock valves hold up? what is the biggest dry kit I can run on a stock motor with only an intake and header? Do the cams they sell for nitrous help alot and how do they run when not on the juice with the nitrous cams installed? Does anyone run the progressive program venom has?

The bottom end will hold and i can't speak for others but i have not had any abnormalities since i started squeezing(i jump between 80 and 100 shots). what year is your eclipse i know certain years can't use a dry shot to to the lack of a fuel return line. the cams are designed to have a longer flow duration for nitrous use so when you squeeze the valves are open longer for higher flow of air/n2o and exhaust gases. I have no clue how they run when not on the bottle. I have NX so no clue on the venow either. sorry i wasn't more help
