    Holley 1850-5

    Try it, the worst that will happen is you'll hate it; OR, you'll love it. Street car, just driving around, enjoying the day, the ride, it will work just fine. Tuning will be required for secondary opening and pump shot.

    273 Carb upgrade

    I threw that out there even though people hate it based mostly on the fact that the OP stated he wanted "a little more pedal" and wasn't looking to dive any further into his engine other than carb and intake swap. Stock 2 bbl 273 is gonna be all done by about 4500 rpm, about the same place an...

    273 Carb upgrade

    In the realm of " a little more pedal and not looking to race " you have actually a lot of choices: you have 66-67 factory cast iron 4 bbl, LD4B Edelbrock, Edelbrock Performer, Holley Street Dominator, even the despised Edelbrock SP2P; they all amount to "more" intake than the 2 bbl on the...

    600 CFM, all I need. Check my math!

    Per your question..........no, your math is not correct, it does not take into account of pumping efficiencies/inefficiencies. You are assuming 100% efficiency and that doesn't happen in an internal combustion engine with out alot of help...... There is more to carburetor selection than simple...

    What does your oil smell like? If it smells like gas, find out where its coming from Make sure you are not sucking air in the fuel line......given that you said you can crank for 3 hours and have nothing.....after an extended crank you should have gas, so somethings wrong there......get gas to...

    power valve block off

    If you are gonna be doing mostly street driving, put a power valve in the primary side. It's purpose is part throttle operation; street driving! I can't say with certainty what will be exactly what you need, however a start would be a 6.5 P/V and drop primary jets 4 sizes from where they are...

    Holley secondaries won't open

    A thought that comes to mind is that you are trying to run thru a 4bbl to 2bbl adapter; I can under stand budget, this is what you've got, etc. It could be a portion of your pain. I've run a Holley 3310 on a 318 in the past with good success, it takes patience. You haven't mentioned what...
