Just finished running in my Hellfire, took a while for me to get all the parts I need to get it running. Have gone through about 3 tanks using the heat cycle method. Not sure how long I need to keep the break in period running? Its taking ages to do the break in, getting it up to 200F, drive for 2-3 mins, shut down, leave for about 5 mins... How many tanks do I need to do this for? Because even with foil wrapped around my engines head, it seems to be taking an age for the fuel to go down. Its using about 1/5th of a tank per 200F 2-3 min run. Is the Heat cycle supposed to last for several hours?!

Apart from that I am very happy, my rebuilt 4.6ho starts first time each time, very happy with it. And the car is driving very nicely so far, even though I'm still only on the break in. The 5955tg on the steering is very quick and positive, definitely what I was after. Do you think I should be ok with the servo saver tighten right up as it currently is or will even the 5955 break with no servo saver?
