Found an LM7 out of a 1500 sierra for 700$ complete engine, everything included. the Iron block aluminum heads version. think i might pounce on this one.

Car Craft mag has done alot of articles on 5.3L boosted(Turbo or Supercharged) engines the aluminum block will save you around 65-80+ LBs.

thats true also, i figured the aluminum block wouldnt hold up as well tho, is that right or wrong? i plan on getting the 5.3 from the junkyard, building my own DIY manifold turbo build with a borg warner 71-73 mm, if i can afford it an intercooler and meth injection. an ls6 cam, with the fuel upgrades. im going to try and do all of this for under 6-7 grand if possible. my own little dirtball special lol. gonna try and run it at about 12psi and see how long it will last. once it blows and im pretty sure it will ( gonna be awesome) i'll then take it out and do the bottom end right if the damage isnt to bad. or just buy another one haha. would the aluminum block stand up to 12psi or would that be pushing it?

12psi isn't much, especially on that small of a turbo, at least for the iron block. I know there are plenty of stock bottom end iron blocks on here with 76mm+ seeing 20+psi on a daily basis.

I didn't think it would be able to take that much . The car won't be a dd , more of a weekend warrior driven to the track and home , and to the local car get togethers with the old fellas around here . Could you link a few of those threads in here for me to read at home ? I'm posting on my cell phone now and can't really search to well

Look up threads by Denmah or skinnies. Those are the guys with the most informative threads on junk yard turbo stuff.
