So this means I really have no choice but to install the Hooker Comps and then swap them out with TTI later. After fitting up the Comps tonight I was ready to lay down the money for the TTIs until I read that tid bit. What a pain to have to take out the Comps. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

If you have a helper... or three ... on hand to start the engine while you, or somebody else, stand ready with a timing light and tach connected , bring it right up to 2000 rpm and get the timing set to 36-38 degrees you should not get the headers cherry red and burn off the coating .

So my headers are cooked.

So my headers are cooked. Mine too when I first started my 440 back in 2005. It's hard not to get them cherry red when you are reving at 2000 rpm for 20 minutes. Use junk headers first during break in. My

Disagree, Under a "no load condition", like braking in a cam you will get the headers nice and red with correct timing and mixture, no way around it. Your running in the idle circuit.

Am assuming that the idle screws we set at 1 1/2 turns to start. I am asumimng that you have an automatic which will put a very small load on the motor.

As long as it fires up instantly without any excessive cranking....5 minutes at a time, or 10 minutes at a time works just fine. Let it cool off between runs, and then do another run until your total equals at least 20 minutes. The idea is to run in the cam and lifters, establish lifter rotation and a wear pattern. The oil and coolant temp, as long as within safe limits, can be on the cold side during the process and it will not do any harm whatsoever. There is no need to melt it down trying to do it all in one shot. Rich H. Esse Quam Videri

When I do my 505 break-in (if I hadn't bought the roller setup) I would have a proven manifold, carb, throttle setup. All I would need to do is set the timing on the mark and I am good to go. Any way you can pull an existing working setup from another car and use the induction side that has the best results? Family owned 1969 Charger R/T DualQuad 440/727/GVO/3.55s

Remember the pump doesn't run in park, the fluid is your lube, and 20 minutes is a good chunk of time. Everybody makes fun of a hillbilly until they need something fixed

Another time I had a fuel leak, another time it was coolant...... Last edited by Frankenduster; 01/24/12 11:06 PM.

This is my first solo build and start up so I am a little nervous. I am ready to get it over with so I know everything is OK. I still have a little work to do to get ready. Mount the electric fuel pump, new carb, new linkage, headers, front end accessories, oil it, valve covers and hook it all up. Question, if I am at TDC and the crank mark is right before zero on the timing chain cover isn't ths a good place to start? ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500
