    electric fuel pump

    I had a Blue pump on the Dart back in the day and it drove me nuts, I run a BG with a return line on the Cuda and it works great. I personally wouldn't run an electric on a driver or stock engine, unless you're having vapor locking issues, a mechanical works just fine and is more than adequate...

    Fuel Pressure gauges and blown carbs

    20% under drive doesn't sound right for a 671, that's a lot, it should be closer to 3% underdriven on a 340 to get around 6psi. I originally set mine up for a 340 with 3% underdrive, but I went with a 416 so I flipped the pullies which made it overdriven 3% and I got about 6 1/2 psi the way it sits.

    Fuel Pressure gauges and blown carbs

    Depending on what drive you're going to be running and how your engine is built, a pair of AVS's won't be enough carb for a blown engine. I'm running a pair of Demon 750 blower carbs on my 416 small block. I have my fuel pressure gauge along with my other gauges mounted to the back of my...

    Vacuum or Mechanical Secondaries?

    Vacuum is definitely better for a mild street cruiser, especially with a 4 gear.

    Age old question: electric, and mech fuel pump?

    No, most electric pumps will block off fuel supply if turned off.

    electric fuel pump relay

    You can get universal 20, 25, & 30 amp relays from your local parts store, they are the same 4 prong relays that Summit & Jegs sell. I got the ones I used on my fans for like $10-$11 for the pair at O' Reilly's. I even bought a couple spares and keep one in my glove box in case I ever have...

    electric fuel pump safety

    A good high pressure electric pump with a return system will always be able to supply more fuel than a manual pump. The idea of running an oil pressure switch to shut off the pump if you loose oil pressure sounds like a good idea, but it won't protect the engine from damage if you loose oil...

    HOLLEY fuel bowls

    The bowls have threads for the fuel line, the float adjuster, sight holes, and accelerator pump. Which one do you need? I may still have several of them out in the garage, I use to buy them up to convert the 1850's to center pivot carbs.

    Thermoquad = not on 318!!?!?!?!

    I think they watched Road Warrior to many times. I go to a lot of cruise nights and they seem to draw a lot of brain dead Hoosiers that don't know a single thing of what they are talking about, I will sometimes go along with what they say and I found it confuses them so they change the subject...

    340 tunnel ram

    I ran the Weiand on my Dart, I think it has less plentum which is better if you are running it on the street. The other advantage is the gaskets that go between the top and bottom are the same as a Dominater so they are readily available instead of having to order one and having to wait for it.

    340 tunnel ram

    I ran a 340 with a tunnel ram in my 68 Dart back in the 80's and I drove it daily and street raced it all the time. They do lack a little in the low end but I think that is all relevant on what you have in the engine. Most of them are designed for the 3000-8500 RPM range which is why they just...
