These are built for your local box stock classes where they require the engine to be left alone but tech is less then acceptable so your left with no option if you want to win.

We start with a 212 hemi engine and then take it apart to do "secret things" to it so it will perform to its maximum potential with that restrictive stock air box. Yes we can do a aftermarket air filter option but please know that once we remove the restrictive air box that there is a better option then using the stock cams.

PLEASE allow up to 4 weeks ship time on these builds depending on work load
