"I recalled a discussion about those '67 traction rods in the Rocky Rotella 1st Gen book." Just a heads-up: that book is out of print and hard to find. And pricey if you do find it. I emailed Rocky at his site Rocky Rotella and he has a few copies left. Send him an email and he will invoice you with PayPal. I ordered mine and it is on the way. I sure miss his articles in High Performance Pontiac magazine.
