    Holley 600 WTF moment---curious to know whats wrong

    No I did not. I have a lot of other work to do on this (intake job again, and 2nd valve springs to go in), so I may still take the carb apart to see, but I won't be putting it back on to run it. My dad (retired 35 year GM mechanic, so he remembers working on these trucks new!!) is building a...

    :happy175: :laughing1: I do want to try to fix it, or at least see if I can find the issue. I won't use it again however.

    Holley 600 WTF moment---curious to know whats wrong

    Vince, sorry I missed that little detail! Yes, new filter (steel one, placed right before carb, about 4 inches of fuel line after this filter to carb), new line, new fuel, clean carb (well, so I thought!).

    Once I get the carb off I will take a look at that. It needs to come off anyhow, and I will open it up and check those items even closer. I had it apart prior to putting it on the intake, it looked really dang good.....doesn't mean it would work properly though as I have found out.

    Holley 600 WTF moment---curious to know whats wrong

    I can only assume you dislike Quadrajets? :anitoof: Yes, fuel pressure is there. In fact every time I would bust loose that top screw to adjust it, a spray of fuel would come out of it. I took the truck out of the garage again last night, but that was after about 10 minutes of effing with...

    Holley 600 WTF moment---curious to know whats wrong

    First off, I am putting a Quadrajet on this engine like I should have done to begin with! However, for my own sake I want to know why the holley is causing problems. It is a holley 600 4-barrel, vacuum secondaries on my 455 in my 76 GMC. No matter what I do, it either gets way too much fuel in...

    What have you done to your square lately??

    Thank you! I feel the same way :Big Laugh: I just thought of this, glad I recorded it a while back!!! This is kinda cool. Here is that same 455, stock, with the exhaust opened up when it was in my 51 Ford Truck (F-1, half ton). That Olds sounded nice then. AND....here is the same link (from...

    We (my dad and I) FINALLY....yes, FINALLY fired this baby up today!!!!!! Here is this sweetheart idling after the break in, and of course...cutouts opened up to hear it clearly :Big Laugh:

    HELPPPP!!!

    Here is what my oil pressure wire looks like (although my truck has a mechanical gauge.....I had earlier clipped this wire from my parts truck anyhow). Here is the temperature sending unit wire.

    HELPPPP!!!

    Updated this below post here 5:20 PM CST.... @NastyRay I have been doing a bunch of wiring myself, mostly done now! I had a horrible rats nest of a mess to deal with as I purchased my truck with no engine, and who knows how many people had their fingers in the wiring. Sorry, off topic here...

    I cannot figure out these two wires!!! 76 GMC

    @Raider L my truck has the TH400 transmission in it, with the kick down wire hooked up from the switch under the dash on the "go fast" pedal ;) As for that wire with the rubber boot, prior to my engine install I robbed that wire from my parts truck, hence the splice in it. I will probably just...

    OK!! Whew, I got a bit worried there...well, my kit is already installed but I thought "ah crap, I need to know this info now just in case!" Thanks for explaining. I learned something new while at work today, now I can go home :laughing1:

    I cannot figure out these two wires!!! 76 GMC

    Whew, glad I am not the only one confused by some of this stuff! Mine does have the TH400 in it. It has a single wire going to the kickdown on the trans, but I do not recall if it goes through the firewall with a rubber grommet, or if through the fuse box/terminal blocks on the firewall...??
