Nehl, is that a real 428CJ ? If it is the heads don't need to be replaced by E-boks---they'll be just fine as they are. The Edelbrocks, uported, aren't really any better than the 428CJ casting. They ARE better than the C8AE-H castings that most off the 360s and 390s got... ...what is the casting number on your heads....IIRC a CJ should have C8OE-N heads. On the intake, I would use a Blue Thunder instead of the RPM Perf, it performs better, and looks much more like factory, and the shaker can will be in the right spot, if you have one. I'd seriously think about doing the oil passage between the pump and the filter pad.......yes it can be done with the engine in the car. Pain in the butt, but do-able. And ignore what the dipstick say, or remark the stick, and run with 6 quarts of oil all of the time. LSG
