Awesome to see the site back up! Hey I'm making my truck in cowboys colors, not with all the aluminum stuff, but I ordered the RPM upper and lower a arms. I would like to get a blue, or blue and silver cooling head. How do I know which one to get? What specs do I look for? There are a bunch on ebay, but I don't know what would be compatible with my 4.6. And if you guys have any other suggestions on other things I can change without sacrificing strength please let me know! Thanks guys, nice to be back!
