jt440...thanks, those measurements are great. The 2836150 intake is an Edelbrock CH4B that someone has ground off the edelbrock logo.

The "OTC" intake you have is the Mopar M1 dual plane. It's supposed to be an aluminum copy of the cast iron '71-'72 manifold w/ a few minor changes. I had one years ago, but sold it. Wish I'd held onto it since they're no longer made.

jbc426...I agree about the torque strap. I have one of the Schumacher straps on my dad's road runner and it works great. I'll see if he will get one of those b/c I know he won't be crazy about a chain or anything that looks too "non factory" on the car.
