    I have a 1999 k2500 suburban with a 454 under the hood. I have been searching the forum to see if anybody in our community can place me in the right direction to see what fuel injectors can I put in my 454 and spark plugs. Has anybody done any kind of performance mods to these engines? I would like to start modding my truck to get more HP.
