New in box. I bought this for a project, but you know how projects go! This is the small block manifold that AFR made 560 horsepower with on their website. I also have the 36 lb. injectors that were also used in the build, if interested for extra $150 ($300 regular). The injectors have 1000 miles on them, but the manifold is new. I've included a stock photo of the manifold because I never unsealed the box. I also have available the throttle body that goes with it, the 1550 cfm unit, 74202s2, it is going for $780 on the interenet, I'll sell the manifold for $450, the throttle body for $600.
