Re: Restoring Rusty
Greg, that leak sucks! Man, I hate when crap like that happens. The new intake gasket looks a lot like the ones I used to seal up my 283, and it worked great. You should probably drain your oil, because I'm thinking coolant leaked down the valley into the pan.
Your new booster hose setup is exactly like what i did on my engine. Nice and clean, with flex hose for the whole run. The carb bracket that loops halfway around the carb, with the spot for the throttle return springs was the style I was initially thinking of. I've seen the type that sandwiches under the carb too, but like you, I'm not crazy about the double gasket. I'm pretty sure that the nut on the end of the fuel line is straight thread with a flare, and not the NPT you mentioned earlier. So the female fitting you need needs to accept a flare and then transition to a barb. I know why you didn't clean and paint the distributor hold down clamp; you don't like painting in the winter! Lol. By the way, stick with the stock hold down. There are fancy pants chrome ones, but the don't have the same friction against the distributor, and are prone to slipping. Good luck with the new gaskets! Greg

Re: Restoring Rusty
That sucks about the leak! The part # 1256 gaskets will work much better with the aluminum intake.

Re: Restoring Rusty
Hey, at least you didn't hang the old gaskets on your wall for "later".

Re: Restoring Rusty
Did you put a dab of sealer on the bolt threads before installing? Not all are blind threaded the ones around the coolant passages I believe are wet. Also oil has been known to weep by the bolts as well, the ones over the oil galley. On another subject I would recommend you put a pcv system on the truck, not only are they federally required on any vehicle after '69, they really are more efficient at keeping the crankcase pressure from building and it will keep the engine compartment cleaner. The blow-by (smoke) the engine makes will end up all over the engine compartment. The smoke is oil based and attracts dust just that much faster. This is just my two cents on this.
God Bless, Terry |

Re: Restoring Rusty
Greg, I agree with Terry, I recommend you put a PCV valve in one of the valve covers and leave the breather in the opposite one.

Re: Restoring Rusty
If there is oily blow-by the last place you want it is going into the intake !!!

Re: Restoring Rusty
so I went to O'Reilly's and bought the right gasket, but they had to drive it over from Stockton so it was going to be a couple hours
fortunately when I came home a delivery truck pulled up, God Bless 'Merica it was my third throttle bracket this definitely put some wind back in my sail even this one has about 1/16 of wiggle room where the others had about an 1/8th of an inch, but at this point I am sure you all is tired of me complaining so it will have to do (but props to the gentleman who said he makes his own, much respect) seriously though I am not complaining I am doing this researching and sharing it so that maybe it helps some of you out too |

Re: Restoring Rusty
staying on the topic of carburetors, the carburetor came with four 1 1/2 inch studs
the brackets came with one stud a hair longer (about the thickness of the bracket) well my intake manifold calls for a split down the middle gasket which just happens to be about 1/4 inch thick so I had to go out and buy four brand new 2 inch studs again this is how the Game is played, you change one thing and it snow balls from there |

Re: Restoring Rusty
whilst sitting there killing time waiting on the gasket to be delivered, I took another gander at the shinny new intake manifold sitting next to me upside down, and I realized it has no rear water passages, what do you all make of that, why not?

Re: Restoring Rusty
finally got the new proper gasket only difference as far as I can tell is that it seems to be made out of black rubber where as the first one was blue plastic
O'Reilly's also had that High Tack gasket glue spray stuff that AutoZone didn't so I snatched a can of it too (the intake manifold instructions suggest we use it on the cylinder heads) I built a wall out of cardboard (being lazy and not wanting to take the valve covers off AGAIN) since the gasket spray adhesive is pink and not clear for some reason this time I wasn't taking any chances so I put some orange RTV around the water galleys around the cylinder heads and around the intake manifold ports followed this dudes video https://www.youtube.com/watch?v=1wVL0cjGmdI |

Re: Restoring Rusty
also picked up a 3/8ths to 3/8ths union fitting and a 3/8ths to 5/16ths fuel line fitting which allowed me to tap into the stock hard fuel line and run a nice clean rubber hose 90* elbow to the swivel inlet on the carb (wish I could find a 90* swivel fitting for the Holley carb that would make it even better)
it do look good if I say so myself someday this is where a clear inline fuel filter will live, but not today, lol |

Re: Restoring Rusty
correct me if I am wrong ladies and gentlemen but I measured the vacuum nipple on the carb for the vacuum advance and I came up with 3/16ths, I got the same measurement on my distributor fitting
yet when I went to O'Reilly's and Pep Boys they had the following lines 5/32 7/32 7/64 now if I use my slide ruler and protractor and convert these so that we are talking apples and apples mine would be 6/32nds so right dab smack in the middle of the first two, I am not even going to bother with the last one as it is tinnny so I bought three feet of each of the first two lines, and just as I predicted one be too small the other too big, and when I compare them to my old lines sure as _________ mine is the size right in the middle of those two you all feel my pain, does that sound about right? |

Re: Restoring Rusty
OK Greg you are killing us, did you finish the truck or what?
Yes, yes I did, and there I was poring the coolant back in when the same thing happened, the passenger side intake manifold flooded... BUT... I did not panic, my World's Greatest Dad (I have a mug to prove it) instincts kicked in and I quickly noticed the genius over here forgot to put the heater hose back on, so I quickly put it on the outlet and tightened the hose clamp, I wiped all the water that pored out and topped off the radiator. Verdict: Intake manifold dry as a bone! Guys I could not have done it without you all, thank you so much for your advice and encouragement, this forum Rocks !!!

Re: Restoring Rusty
Then I went to start the truck, and it would not start, I figured no gasoline in the carb, that must be it.
Reached for the starter fluid on the top shelf only to realize it was all but empty... quick to the lawn mower red can canister, EMPTY There's Ed our neighboor hey buddy can I borrow some gas, sure, here's my barely any left lawn mower red can, ... Thanks that will do Pored that down Rusty's throat but he still would not start Double and triple check the firing order since I took the plug wires off the distributor cap (they were on right) Man I bet I did it again, I am notorious for putting the distributor in one tooth off, I did it on our '97 Tahoe I bet I did it here, yep sure as _______ that was it After the distributor correction he fired right up - I did absolutely nothing to the carb, now that is Holley Performance magic ladies and gentlemen, outstanding I set the initial timing at 13.5* BTDC at 650 RPM, I swear it sounds like the New York Philharmonic playing the sound track to a perfectly tuned Chevrolet Small Block 350 cubic inch V8 Well did you drive it? Heck yeah I drove it, it runs soooo good. Thank you all once again, I appreciate all the help soooo much and I am so happy, tired, dirty, but happy. |
