Crane makes the current GM replacement cam, which can be found here

Wink Re: '69 DZ302 cam

Greg what Eric is saying is you can order it from GM, but GM will send you the cam made by Crane. GM no longer makes this grind, but uses Crane as their supplier for it. There is no OEM 302 cam any longer unless you find an NOS one, which do appear occasionally for sale. So you might as well just buy it from a supplier like Jeg's as Eric suggests.

Clevite also offers many of the original GM grinds as well, but are a little more difficult to find unless you know the duration, lift and valve event timing info already for the cam you are looking for. I used a Clevite replacement for the last 302 1st design off-road 140 solid cam.

Thumbs up Re: '69 DZ302 cam

All good options........I used the Crane Blueprint cam and recommended springs, ordered from Summit. It worked out great. Just make sure you use the "JOHNZ" method of valve adjustments. Mine are "solid sounding" if you listen close enough, but not at all noisy.

Comp Cams also make an OEM replacement.
