Hooker makes a kit for it with motor mount and trans mount . They discontinued the headers , so you'll have to find some used ones . I have a bunch of pics if your interested . I fabbed my own mounts and used 1st gen Camaro motor mounts and extended the trans mount from materials i got a the hardware store . I also used a Hooker super comp block hugger . My truck also has an HEI in it . Here are a couple of the mounts . Trans mount
