hi i am knew to the site. i have a 440 with12.5:1 compression p&p head,stage 2 hot cam, open aluminum air box,kibblewhite valve springs, i believe thats it. i got a dynojet jet kit and i just didnt know if i should follow there instruction or what any help would be nice

do a search on it. There are a ton of posts on this. Im not too sure if the jet kit will work or not. They usually dont have large enough jets for 440's

i did try to search ad couldnt really find anything, i was gonna go with a dj170main with a 40 pilot and the needle on the 3rd notch from the top with the fuel screw 3.5 out

if you are running a stock exhaust, i would start around a 170 keihin main, and a 42 pilot, needle in the 3rd spot, air screw 2 turns out.
