Hey Guys, I know that I ask a lot of questions. but I'm trying to learn all I can about my truck, like what is the horsepower, and the torque? My brother-in-law has a 77 ford 4X4 with a stock 400 in it,-:t
I know that my truck would pull himfrom here to California if he would quit making excuses and hook em up, but I would like to h
ave some numbers to add a little fuel to the fire.

190HP and about 380-400torque(don't know torque number off the top of my head). Put an exhaust and open up the intake and she'll be a whole new engine you didn't know you had.

his sig says he has dual 3 inch out the back door. open up the intake in which way, how, where. mine has a k & r air filter.

I have straight exhaust now, so what I can I do for more? And what about the Intake? I seen on here where a guy took a dremil tool to his turbo to open it up(where it sits on the intake), is that safe, and does it help out much?

The stock downpipe is the major restriction in the stock exhaust. As has been said here many times before, it looks like they ran it over with a fork lift before they installed it. Click the link for airbox mods. http://www.kennedydiesel.com/airboxmods.html
