    CARBURETOR DATED

    Biggest issue is the carb getting heat soaked in my experience. Get the spacer.

    Gas hog

    If you read he asked specifically about the AVS2 that you don't own. Not what YOU like or are gonna do . The standard performers don't have annular boosters or an adjustment for the secondary. Facts.

    Gas hog

    I've had one on my non squarebody daily for 5 or 6 years. Hit the pedal twice, start it and drive away. I've had to adjust the choke and idle mixture screws, change to the pink stepup springs. The secondary is adjustable unlike the standard/AFB carb and has annular boosters. They are somewhat...

    CARBURETOR DATED

    It's heat soak and the ethanol gas. Get the Edelbrock 4 hole phenolic spacer. It comes with new gaskets and studs. The metal braided hose/cover on the fuel line and filter location isn't doing you any favors either. Truck looks good. What size rear tire is that?

    Changing gear ratios: opinions/suggestions wanted!!

    Overdrive ratio between the 700r and 4L80 is .70 vs .75. Barely noticeable. Those RPM numbers are off.

    Icing on the cake !!!

    You don't have a local parts place in case they dont work? Usually they'll let you pick through what they have.

    Icing on the cake !!!

    I'm 100% sure they are not shaped the same as what you have already. Good luck lol

    Icing on the cake !!!

    Factory SBC Vortec trucks/suv (96-2000) have the same style bypass. One of the preformed hoses from them may work.

    Proportion valve question

    You're welcome. As far as I know the booster is the factory one from 79

    Proportion valve question

    I don't know the difference if there is one. Right Stuff didnt show a PV4 when I was looking so it may just be the way they number theirs. Master cylinder # was NMC2300 from Napa...79 Corvette, 1 1/8" bore for power brakes. The 1" bore is for manual brakes and has a deeper center portion on the...

    Proportion valve question

    I used this one on mine with a C3 Corvette master cylinder. Line sizes and mounts just like factory. https://www.summitracing.com/parts/RSD-PV72

    Chevy orange slanted Pro-form valve covers

    VHT Chevy orange nor Duplicolor Chevy orange matched the Proform orange on mine. I wound up painting over the powdercoating to make everything the same.

    The Best Carburetor?

    I'm sorry they refuse to let us in on the secret. Makes you wonder doesn't it?

    The Best Carburetor?

    Q jet guys are gonna say they're the best because GM knows all and people who don't like them don't understand them. They usually have a cousins/sisters/brothers former roommate that was a w-h-i-z with a Qjet. Coupled with a 700r4 and 2.56 gears you stop at gas stations to unload fuel not fill...

    Swapping out OEM distributor with HEI distributor

    Ricko I know theyre the same distributor more or less. We bypassed it on my dad's 85 GMC and eventually stuck a regular HEI in it with all new stuff in it when it went to my nephew and set it like every other SBC prior. My thoughts were they had a real low base timing (like 6 or 8) to drive up...

    Swapping out OEM distributor with HEI distributor

    Old doesn't mean bad, new doesn't mean good. Mine and countless others run great without it. High compression and all. We agree to disagree. :happy107:

    Swapping out OEM distributor with HEI distributor

    They went to EFI and coil near plug too. That ain't got jack **** to do with a 40 year old truck with a carb on it though.

    Swapping out OEM distributor with HEI distributor

    Yes... I was being sarcastic lol. If it's detonating you have the wrong timing in it, especially if it's 4, 6 or 8 degrees too much. When do you get the power back from it detonating because you have it wrong? Common sense says adjust the curve instead of putting a bandaid on it.
