1237318 ('70 model year) castings with the following date codes K8 M3 M17 For reference, my 10E bodied car has a J9 intake which seems kinda early (???) & it's certainly possible it's not the original intake as I know the engine was rebuilt 2x in its lifetime, but I'm also almost sure this car has never been anything but a stock Stage 1. $100 each plus the ride. Located near Baltimore, MD. Free delivery to GS or BCA Nationals.
