    Okay. Online I can find all sorts of videos to tune a Holley carb with the top adjustment screws. My Holley 650 Classic does not have those screws on top of the bowls. I have gas leaking out both sides the throttle shaft of a recently rebuilt carb. It only leaks after driving a few blocks. Does...

    My 84 K20 has a 502 BBC, it ran strong then started dying at stops. It got so much worse it doesn't even run now. I changed all tune up componets, even put a brand new distributor on, same thing. I assumed it was the fuel injection so I took it off and put on a Demon 850 carb. STILL, same thing...

    I need a new carb for my Camaro. It's a built 350 with Vortec Heads and a LT4 Hot Cam. The motor should be around 400hp. Should I go with a QJET or a Holley? My dad said both work well and its my choice. Its a 5 speed and its a weekend fun car. I want good throttle response and decent gas...

    I was advised to buy a fuel to air ratio (Fast or Holley ) wide band O2 sensor hook up to tune in my carb. Does anyone have experience with any of these or recommend one over the other? I am getting black smoke and black plugs plus smelling like exhaust after driving the car. It's a 700 cfm...

    Long story short - I am thinking about buying a car and wondering about the engine build. It was owned by an old hot rodder and he has passed away, and his daughter who inherited the car is a good friend of my girlfriend. She doesn't know anything about the engine other than a plaque in the...

    Hey y'all, I bought this Holley 4160 600cfm vac. secondary carb. It looks like someone tried deleting the vacuum function because the hole for the diaphragm was sealed up and there was a screw on the throttle linkage for the secondaries that was adjusted all the way to open with the primaries...

    Was searching craigslist for a roller long block and ran across these Holley heads. So I did a google search, as I do with all craigslist parts that interest me, but found NOTHING! Poster did not include casting numbers. I didn't know Holley even made cylinder heads. Anyone heard of these?

    Alright so I've been ALL OVER the internet trying to find a good answer to this and I really haven't come up with much. How do you find your secondary jet size (with max HP in mind) on a traditional Vacuum Secondary Holley 4 Barrel without an AFR gauge or a drag strip to evaluate E.T.'s and...

I just bought a 79' Malibu that was a steal of a deal and i couldn't pass it up. the guy i bought it from said the starter was bad so i changed it and it cranks fine. I couldn't get it to start without my foot all the way to the floor and it would not...

    Hey guys. I have a mild 350 sbc in my street rod. Really do not know the specs on the motor. But it is no street demon for sure, just a simple cruiser. I installed a 750 double pumper on it, basically because it looks really cool. It came with #74 jets. Had a hesitation when feathering the...
