he351/s475
I am going to build a healthy diesel..
im getting ready to tear down the truck and refresh the bottom end.. ill o ring and stud the heads.. also port and polish the heads.. im going to add a port to the intercooler so I can get more flow in and out. im going to make a custom 2 horn intake manifold.. ill be doing all this hopefully to make reliable power. my questions are: 1.) is the HE351 over a S475 a good setup 2.) how much boost will this set up make? 3.) what motor mods do I need to do to make my truck get them most out of the boost? (larger valves, cam, timing, and more?) 4.) I plan to open the waste gate port on the 351 but will it be enough to reduce line pressure? |

I guess 600 hp seems like a good number...
my sold dodge that is in my discribtion ran very nice but a little hot.. I would like to have a little more power... so never having it dyno.. what power do you think I had? |
can any one clarify what the difference is between a S475 1.10 and a 1.32?
I have searched all over the Google and cant find the answer... I am also looking at a S475 vs a S472 if any one with experience has used these turbos |

Since your already planning on porting your head you wont need any other motor mods to hit your goal.
