Break-in fluids
Shell Rotella 10w30 T4 is a good heavy duty oil for break ins. Has the good additives. Good for a diesel good for a 440, along with your zinc break In additive. Thin enough to wash out the fines as the engine is breaking in.
Carquest Premium tall oil filter 85515 (fits mopars, 440 too) with the red silicone anti-drain back valve is one of the best on the market. Keeps your oil system full on startups so you don't get that valve ticking when it first fires on the restarts.
Would be great to prime your oil system with that filter on there, then it's full and ready to go all the way up to the lifters.
Good to just have the single valve springs on to lighten the load on the cam as it is breaking in.
