truck is lookin good  

Nothing wrong with a High schooler beatin on IFS, I'm still doing it, and I've been out for 3 years

Nobody is knockin on your build, they're just making some suggestions based on their experience. 

Running aluminum blocks can be dangerous, and they are hazardous to other people (I've been hit by one squirting out on the freeway!! )  Glad to hear you're only running them for a little while, you may want to look into chevies if you're tight on a budget, I've got them in the 63" flavor, and they kick   they hel make up for the lack of flex on the IFS

Don't worry about the constructive criticism, no one is out to bash you, but if you get your panties all tied up in a bunch, more and more people will.  This is a community, and if you can't handle some funnin' and a little constructive criticism, you won't last, because we're all about joking around on here, while offering up some kick tech

If you've got any questions about your IFS, let me know.  I've been running it for years, and I've broken, bent, or worked on pretty much everything

Rig looks good!
