400 into 65 valiant

Drop it in with HP manifolds... or cut the inners out and run a real header then fab an inner thay fits your headers. Tie the shocks with hoops off the front frame arms like a modern truck. The streetmasters are dimensioned out somewhere in here (by me) and are literally 2 nested U channels connected by a bolt to resemble a hinge. The pic in this thread is the same ones I used and would be very easy to fab up. If you can actually get the motor back about 3 inches toward the rear, stock b headers will fit the passenger side! Only hangup i had with Pro-Parts semi fenderwells were the tubes to the collector came right across the idler arm arc. If the motor was back 3 inches the tube would have rode right over the arc and dropped into the collector as a 67 would fit with its front wheelbase and steering forward 3 inches. Thats how I saw it when I ran mine. Driver side was a complete reroute of 1 tube around the same pitman arm interference. RB is going to get your headers out a tad farther than a B and off the pan rail as they seem to be designed for a RB as mine hit the pan rails and I had to clearance a tube so they would seal up top. It worked , it was fun, dangerous as hell as the slightest gas in a turn would break the puny fender shrouded tires loose in the back, and didn't last long as I had to give the loaner 451 motor back to its owner once he got a 69 Barracuda project. He gave me the 340 that was in it for payment for saving the 451 from the big padlock of the storage wars guys. He lost a 64 Barracuda 4sp (with no motor) to those guys. He was overseas and called me frantically at about 3pm to go get what I could before midnight! Loaded the breakdown cherry picker into the back of my Diamante and snagged the motor out of the car and a few carbs and a bunch of his tools alone. Couldnt get the trans out.. Bummer for him.
