350 stroked

[littleswap]

I have just stroked my 350 to a 383. I have also added headers and a free flowing exhaust system. I am trying to rework the fuel system. Looking at adding bigger fuel pumps and reprograming the computer. I would like to put the correct throttle body on top. This truck could be a daily driver. Do I need one off of a 454 or just install bigger injectors????

Isn't it just a matter of re-adjusting your fuel regulator? Then again the computer should re adjust based on the O2 sensors and the MAF. You did reinstall the 02 sensors with the new headers?
