the nozzle will work in your app. only way it wouldnt would be if you had carburation in wich case you need a plate. It will go in your intake tube prefferably 3-6 inches from the throttle body. as far as the numbers, there jet sizes, if you call holley{nos} they can tell you what size shot they will give you.http://www.dynotunenitrous.com/store...ousjetcalc.asp

this is a good place to find out what jets you need for your desired shot anyways goodluck hope i helped.
