Hi i am wondering what kind of hp should i be pulling out after i modd one of my engines.. its a 400ex engine... stock for now.. im sending it out this summer to get the work done.. a 440 kit 13 1/2:1 compression,, web cams, port job, 1mm over size intake valves, k&N filter, FMF powerbomb header with FMF silencer,, 6mm stroker crank,, so that would make a 460 or a 470 i think,, weighted flywheel, Big gun rev box.... then what ever carb i need i will get.. i will just call carb parts wearhouse and they will set me up.. thats about all i can think of for now.. im looking to run with the 450's or even out run them.. mainly the yfz... would this put me where i need to be?? thanks.. i think the 400ex is 30hp stock?? or 28hp somewhere like that....
