Mild Built 1979 W72 Pontiac 400
After a personal deal falling through, I have decided to post my Pontiac 400 on the public forum. This is a mildly built combination but it makes awesome power. It actually makes more power than my stock LS1...no joke there. I previously had an aftermarket intake on but I have been in the process of putting a stock intake back on. That is why the intake and valley pan look ugly. I have roughly 7k miles on this combination....not that much run time. Great for anyone trying to restore a '79 400 W72 Firebird or someone simply wanting a strong street engine. I did this build in about 2010 and I roughly put $4k in this setup at the time. This will be intake to oil pan (no carb or ignition) with front accessories.
Also, this is from a non-air conditioning car so it has the metal hose bracket rather than the a/c components. Another difference over the a/c cars is it has a straight fan without a fan clutch. Bottom end... 1979 PWH Code block Block deck milled +.030" KB Forged Icon Pistons ARP rod bolts on stock rods Top end... 6X-4 heads milled to 87cc combustion chambers Converted to screw-in rocker studs with locks on the stock rocker arms Lunati Voodoo series cam shaft $2500  Untitled by Jonathon Randolph, on Flickr

Still available.
I popped off the valley cover to show it still looks brand new inside and then did some detailing on the outside. Again, this is a well built engine. Also, I forgot to mention in my initial post that it has an aluminum Flow Kooler water pump.  Untitled by Jonathon Randolph, on Flickr Untitled by Jonathon Randolph, on Flickr

Would you swap for a 350 and a 455? Both needing rebuild but including #62 heads
