I like how the p400 opens exhaust later. I think this is one of Heath's tricks . I bet the exhaust opening point could be 10 degrees later,for more torque. This would dramaticaly change turbo exhaust turbine requirments.
So I would like to try it again, with like .600 lift , and stock duration. A long time ago I had checked things and it looked like it would work , with different springs obviously. Feel free to post up any cam specs you might have,since one of our cam threads got deleted .
This is the cam card from my first cam. It had way more power,and super quick spool up. But had egr from overlap,so it started hard ,and ran off of its own exhaust . Basically it ran horrible untill the turbo spooled.
I assume you know there are 2 bypass valves, the hidden one is for the cooler,and removing the freeze out plug that forces oil through there will majorly increase oil psi. But then the cooler is deleted.
Before I figured out that it needed a bleed hole, I was just using a regular 1060. If you would leave the bypass open totally, then lots of dirty oil would get to the bearings.
I just disassembled two 6.5 heads ,and they were just on the exhaust valves. I have at least 6 more heads that are like that. Just make sure you don't forget the orings on the valves without seals .
I have ran both ,my favorite is the 1060R . On this motor the cooler is deleted ,and freeze out plugs in some of the holes in the block. I didn't decide yet on this 506 build ,but probably will use the 7202,and plug off the stock bypass.
I have mine blocked,with a tiny hole drilled in it. Without a bleed hole , sometimes after an oil change,it would loose prime,no psi untill I would loosen the filter and bleed it.
I used the cam ring and pin. Its very rare for the shut off solenoid to fail. Only ever had one go bad. If you dont want to take the top off,check amp draw ,should be 2 or 3 amps.
