I spent a couple hours clearing our some storage and shelving in the garage and moving to a storage building out back.....and there just s happend to be enough room to bring my engine stand back into the garage.......hmmmmm.
And back on topic.....+ 1 on injectors and tune.
Did you change injectors or use the origninal ones? Also, get the specs on what you did to Sean and Hemifevertuning.com and see what he can do for you. That thing ought to run like a striped ape when you get this done. What did you do for intake?
And _ +1 MORE on pics!!!!

Scat 408 crank, eagle rods, KB hyperutectic pistons, comp cam gross valve lift .480 duration @ .050 212 intake and 218 exhaust. Stock intake manifold, stock injectors reworked by dr injector. Sounds like the machine shop screwed me telling me the stock computer tune will work fine.

Stock fuel system will feed a 408, but not the stock injectors and you WILL need a SCT tune to make it work, as said your fuel sync needs to be set, but where you set it depends on your build. +4 is safe.
More info on the build please....And quit trying to run it before you kill it.
Just dropped a 408 in my Dakota this month....412 RWHP

How do you set the fuel sync.

Stock tune+bigger injectors+fuel sync not set+48 more cubes is gonna run like garbage.
Drill the holes bigger with tiny dental drills. I have a set of 42lb injectors from FIC that were modified from their stock size. They're flow matched too.
