hey Tim, i picked up an Eddy truck intake awhile back. its one of the original models, lower has 3880 part number. Anyhow the upper only has the vacum tree port on top and the pcv valve tube runs to the back kinda like the 88 model intakes. was your like this also or did it have the pcv running up to the side or top of the plenum?
Thanks for your time
Travis
