Chevydafz1 Sounds like your in for a fresh engine. With little experience at engine work,maybe a good used engine or if you done a crate engine (if available to you) they would require some credentials on who installed it. In the US would be some professional installer. Best bet for the money would be good used if you can switch em and I would want to hear and see the used one running and drive it. In the days past you didn,t want to test engines for the junkyard !! It's easy for them to say oh we'll get you another one !!!
