I did something similar probably about the same time. Get this......guy had like an 81 or so W150. 318, auto , all stock. Had big tires.......38s I think. Probably 3.55 gears. He was referred to me by another friend. He wanted me to "make it sound good" and stop burning oil. It needed the heads redone, so I did all that. Then he "took it upon hisself" to order the 508/292 cam and lifter kit. LOL I tried to talk him out of it......nuthin doin. I did make him get good valve springs and a nice timin set, though. So I get it all back together.......new headers and all and it sounded really shag nasty......and actually pulled pretty good. I was surprised. It was a little soggy right off idle, but other than that it was ok. He loved it. My point in all this rambling is, I used that same intake "up there" which is a 73 340 intake. His had all the EGR and whatnot on it and he wanted that deleted. He loved that old truck. It was nice, too.
