i picked up an 05 with a snapped crank from a hydro lock! Other than that it's in good shape I just picked up a crank for 400. and am sending it to the machine shop for a little TLC and some secret parts!
Now if someone would tell me why they make a 50mm head gasket?? is that for cams with extreme lift? Not that I have one

very nice, great pictures. hope it works out well! one thing i noticed is the placement of the egt probe. I thought it was better to have it twards the rear of the manifold? i drilled mine in the 5th port? maybe i screwed up, thought that the rear was hotter for some reason?

yeah the rear get's hot faster under heavy load I put mine where three would give me the best average. It's strange the probe is right by the cylinder that melted and never did it go above 1000 degrees! makes me wonder what the probe actually reads! So far so good! ran her hard today and still feels good! that's a hundred miles at 70 to 80mph! Purrs like a kitten I think I got lucky!

Thats great to hear! Glad its running good. Not to hyjack your thread, but what typically do you get for egts? i know you got alot of mods, i can hit 1600 wot@ 110mph, my 97 dodge never hit 1400 on the street and hit 1600 only on the dyno. Just wierd to see it hit 1200-1400 with ease. i only have 4" straight pipe, and cold air intake, with smary on catcher 4 with trq managment and all the safe modes on the light side.

The third gens burn alot of fuel real hot! 1400 for 10 to 20 seconds isn't going to hurt anything! Before my water injection i would back off at 1350 even though these engines can run at 1200 all day long! With the water injection I'm lucky to pull 1100!! that's at WOT! I think big air in and big air out makes a big difference! The boost with the meth/ water is pretty silly to! 40psi is no problem!
