I am going to rebuild the Chrysler industrial 318 in my 85 Tucker 1342B. A few guys have told me to change the Cam to put the power band around 3000 rpm. That is about where I am when grooming. Any thoughts? I was going to have it redone all stock, but now not sure. I sent an e-mail to Tucker in Oregon and waiting on them to get back to me. I know everyone here has an opinion! LOL
