WILL HAVE PICS UP TONIGHT! Getting very close! Heads came out great from the machine shop. The Tick Performance package was great bang for buck. Brian Tooley head components and good cam. I will post the cam spec sheet also. So we kept the stock bottom end as planned. Motor is back together and looking great. Ending up tapping in a CTS-V map sensor. We are waiting on the conversion harness for the throttle body at the moment. I ended up getting the Dirty Dingo manifold and cross pipe. Its really great fitment and the short stubby design supports my big frame borg warner really well. Only modifications will be moving the 44mm wastegate back on the manifold a bit because the 4in down pipe will hit it. I went with 275/50r17 M&H tires for the back on my Truck Star wheels which look really good mounted up. At this point we just have to do the downpipe,dump tube, intercooler & set up the fuel system. We are shooting to be tuning next weekend. Going to start with a pump gas tune with the 7psi wastegate spring and see where we stand. After dialing in we really hope to see 600-700 on pump gas at between 7-10 psi. Pics will be up in a few hours

 

600-700 on 7-10 psi 4.8L, that's a typo right?

 

great project man...... depends how much you wana push it we are pushing one of our trucks up to 885 on the 4.8.... as longest u do everything right u should be good good luck

 

I think on that 80mm BW with all the other supporting mods and really good tune we can see close to that. Probably should have just said around 10"ish" psi but we will see. Like I stated before this is my first auto v8 build. I have a really good tuner and good quality parts so I just want to see what happens and how far we can push the stock block before going with a different one. Take it easy

243 heads came out great!

 

Turbo mounted up with the dirty dingo manifold and cross pipe

 

This setup doesnt look half bad. Really like the M&H tires.
