Re: Restoring Rusty
Thanks for all your efforts to document this process so well, with descriptions, humor, and photos. This will be handy for my son and I one day.

Re: Restoring Rusty
then I took some more pics of the old OEM intake manifold realizing I done never flipped it on it's back to take a pic of it's there belly
now if you look close you might could just see how the EGR port is all carbon dipossited shut right there in the middle of it, completely shut to the point of ineffectiveness |

Re: Restoring Rusty
so here are some before and after pics of the cleaned lifter valley (wish they turned out better - my garage faces West and the sun shines right on my back and cast shadows over the engine bay, poor me a river! right)

Re: Restoring Rusty - Intake Manifold
I want to point out something to you that I learned
the new aluminum intake manifold is thinner than the old one, at the pint where the bolts go one is 1/16 of an inch thicker if not a bit more also I am not planning on putting on the bracket back on so I noticed that those bolts were an inch and a quarter and the other ones were inch and an eighth also some of the bolts don't screw all the way in the two that surprised me were the bolt above the #4 exhaust port (third bolt in the passenger side head) it interferes with the exhaust push rod and the bolt above the #5 intake port (fourth bolt in the driver side head) it inteferes with the intake push rod |

Re: Restoring Rusty
now maybe with the gasket and a prayer these components would never meet, but that was a chance I was not willing to take, so I picked up some shorter 3/8th grade 5 bolts, only one inch long and some washers to remedy this situation, I used these in these two places plus on all the outer corners as those bolts bottom out (blind I guess it is called)

Re: Restoring Rusty
so first a dry fit, just to see if the holes align and what the gaps are like

Re: Restoring Rusty
at this point it was getting late, I was cold and hungry, but there was no way I was going to stop here
so we will be using another FelPro gasket (but not all the pieces just the blue sides, per Weiands instructions we are NOT to use the middle pieces) I could not find any gasket adhesive maybe I was looking for the wrong stuff, I imagined it would be in an aerosole spray can, anyway I needed some stick-to-it-avness so I just gently coated the heads with RTV silicone then I ran a 1/4 inch beed of RTV down the middle as per the instructions I used carb cleaner to clean all the grease off of all the maiting surfaces (AutoZone was all sold out of Brake cleaner, can you believe that that's like an Irish bar running out of booze) |

Re: Restoring Rusty - New Intake Manifold
torqued all 12 bolts in the super special sequence using a torque wrench first to 10 ft lfbs then to 15 and finally to 25 ft lbs
only one bolt gave me trouble to torque to spec that pesky third bolt from the front on the passenger side, the intake stack is perfectly in the way on that side, it seems to be set more to that side than the driver's side, oh well I eye balled it in the end and the money shot |

Re: Restoring Rusty
at this point I hit a Mechanics High, I had to keep going I had to see the carb on there tonight...
so first the studs went in... then the split down the middle carb base gasket... then the crown jewel... the Holley Carburetor |

Re: Restoring Rusty
still far from being done with this phase, got to put the dizzy back, connect the vacuum hoses, thermostat, coolant hoses, throttle linkage, even a bit of electrical to do ~ but it's so rewarding at this point!

I literally chisled the cross/bypass ports in the cylinder heads (what I call the EGR ports) open, they were completely welded shut with carbon deposits, or what I can only imagine is carbon |

Re: Restoring Rusty
Awesome! While I am partial to the old quadrajets for daily driver rides, that carb does look quite at home up there.
