Well the other on the street fighter engine got me thinking, which is a bad thing. What would be considered the best engine parts package to build for a daily drive, worked and trailer pulling truck. My current engine just rolled over 40K and its lived its life on the 500hp or 600hp tune, so I really need to start thinking about a new build. Air probably would be compounds and fuel would be 45%-100% over SAC's. What would everyone recommend for a build.
