Swapping out the stock 6NZ camshaft for the 10R7155 cam, better known as the 800 horsepower marine cam.

This was just an experiment to see for myself if I would find any immediately noticeable negative effects from running the 10R7155 cam with stock "57" injectors. This is an improper camshaft to injector combination, as I briefly explained in this video.

In the long run, this combination will cause accelerated internal injector wear, accelerated cam lobe and rocker arm/roller wear, and in some cases can eventually cause catastrophic gear train failure as it shakes the weights out of the cam gear due to increased harmonics coming through the cam.

The 10R7155 camshaft properly matches to a "59" injector, which is a much higher flowing injector than a "57". There is very little to be gained by running this cam with "57s", and it will only cause problems in the long run.

Do not mistake this video as me telling anybody that this cam swap alone is an upgrade or something that you should do to increase performance. That is not and never was the intent of this video.
