    6-BBL / 6 Pack & Hemi 3/8" fuel line FUEL VAPOR SEPARATOR/FILTER w/Braided fuel lines. How to incorporate as factory did? Or don't bother?

    @RJRENTON @HEMI-ITIS @davek @6PKRTSE @68 HEMI GTS @66Satellite47 and I'm sure I'm missing some of the best who I hope will join in this thread... Here's the story, and I believe I need to change up my configuration: When I got my V-code 70 Roadrunner, it already had the (very nice) WIX 33033...

    I guess I'm eliminating the fuel vapor separator from my 70 440+6bbl

    I was going to reinstall the fuel vapor separator, but the shop saw the line was plugged off and he cut the return line way back by the tank. The owner says when I install my 541 stroker the Carter M6903 120 GPH mechanical pump isn't going to provide the required fuel reliably. He says that the...

    Max Wedge port single and dual plane intakes? 6bbl??

Also, does single plane necessarily mean poor street performance when the rest of the engine is a well balanced, complimentary selection of parts and performance? I...

    Innovate Motorsports wideband O2 system installed! Question about 6bbl intake

    I have the gauge that shows both O2 sensor readings in real time as A/F ratio or Lambda. Since I have the Edelbrock/Chrysler aluminum 6 bbl intake, which side of the intake feeds which side of the engine? Does the intake cross over or do the carburetors mainly feed the same side of the engine...

    Clear plastic fuel bowl site plugs...a warning....

    Many of you will know this. I left 3 clear site plugs in the fuel bowl sight holes longer than it took to check and adjust the float levels. I won't make excuses, I knew I shouldn't leave them in "too long"... Well any longer than it takes for the actual same day session to adjust the floats is...

    Check out the G-Surge Electronic Fuel Pump! 12/3/2018 Installing the FiTech 3x2 system

    I am starting a new thread even though Don Selleck is doing a great service to the forum by detailing his install. Here's an article about the FiTech 3x2 system installed on a 71 Challenger, originally a 440 6bbl (just like my 440). I haven't even read it yet, but as soon as I post this I'm...

    This is about non-Mopar in this instance, but a local car show attendee I know had All American Carburetors rebuild and RESTORE his 2 x 4bbl carbs for his big block Ford V-8 in his AC Shelby Cobra and he swears by them, their performance, and they do look great!
