There are carburetor spacers available with a built-in PCV hose connection. This is just one of several different ones available from Summit... Trans-Dapt Performance Products 2584 Trans-Dapt Performance Carburetor Spacers | Summit Racing

"Down under" carburetor

Just slightly off the subject...has the company given any thought to single-4 bbl. billet CNC machined air cleaner assemblies? I would think they would have a much larger market.

Did anybody check to see if there is actually fuel in the gas tank? Years ago I worked with a lady who had just bought a brand new car, drove it just a few miles from the dealership when it died and wouldn't restart. The dealership had it towed back to their service department and spent 3 days...

I know it doesn't sound like much of an increase to go from a 5/16-dia. line to a 3/8-dia. But it's a 44% increase in cross-sectional area. So, yeah, it is kind of a big deal.

I agree with both sireland67 and j par regarding the Street Demon carbs. If all you're interested in is cruising then i think it's the best carb for you. I also agree with dano, don't but a carb from Classic Industries. Check out either Summit or Jegs for best price and much better customer...

Hey 'crash' - Long time no 'talk' to. I was going to start a conversation with you to keep from hijacking this thread, but your inbox is full.

Sorry, but I have to ask...and I apologize in advance if this is a stupid question. I understand the 3/8" line currently from tank to pump, but why the 1/2" line from current mechanical pump to carb? What's the benefit of the larger pump to carb fuel line?

Pics of your needed parts might help...

This is the one that will be going under my '69 Dart... Hot Rod City

* Car: '69 Dart * Planned engine combo: 408cid, 10:1 compression ratio, EQ Magnum heads with 62cc chamber and 2.02"-dia. intake valves, cam specs 230 in./234 ex. @ .050 w/108 centerline .501 in. lift/.513 ex. lift, Edelbrock RPM Airgap intake, TTI 1.625"x1.75"x3.0" step headers, 3.0" exhaust...

Good points all. I was wondering mainly about the port airflow velocity between a single-plane and dual-plane manifold considering the size difference between the much larger single plenum of a single-plane intake compared to the "split" right/left plenums of a dual-plane manifold.

I noticed the kit includes a single-plane intake. What's the thinking between single-plane and dual-plane intakes with sequential EFI? Same street-friendlier attitude with dual-plane intakes and EFI? Or does it make any difference?

What I noticed in the video was it seemed he was working the throttle quicker when the "atomizer plate" was installed. That's what caused the quicker revving.

Yeah, close dimensionally but a fairly large difference in cross-sectional area. -6 (.375" dia.) tube/hose is 44% larger that .3125" dia. tube/hose in cross-sectional area, so theoretically should flow 44% more volume. Correct?

Hey Johnny Pace - If I understand your comments to MuuMuu101, the stock 5/16 gas line is too small to use for the return line to the tank? Please confirm. Thanks!

I talked to the Demon carb folks at SEMA a few years ago about my thoughts that annular boosters may get better mileage because they're more sensitive to signal changes. They confirmed that was accurate.

I know of several 850-cfm Thermoquads that may be for sale. Sorry for my ignorance but I've never used a TQ and don't have any idea what they may be worth. Can someone please school me? I know about their design and all - just not their worth. Thanks!

As mentioned before, contact Leanna at Phoenix Specialty Coating. I've talked to her before about a clear powder coat on an aluminum intake and she said the same thing about yellowing. But she has silver powders that look like blasted bare aluminum and they won't yellow over time since they're...

Hey ecurb, contact our resident powdercoating artist. You won't be disappointed! See her outstanding work on her website: http://phoenixspecialtycoatings.com/ I've shipped parts to Leanna from SoCal so she can work her magic and it was well worth it.

Just to give you something else to consider... 625 CFM, small primaries, vacuum goggle-valve secondary. Here's a link for more info: http://www.demoncarbs.com/1902.asp

From what you said in 360duster's thread I was sure you'd already pulled the trigger and ordered a new 750 Street Demon. I always ran a Holley on my first '69 Dart. In fact, I started off with a 780-cfm vacuum secondary 3310, then went to a 750 double-pumper and finally ended up running a 850...

You can also use phenolic carb spacers to help insulate carbs from intake manifold heat. Available in both open and 4-hole designs from Summit and others.

I'm guessing somewhere in the Folsom area based on MOPARoldtimer's info

that will fit the stock '69 A-body fuel tank opening without modification? I know it's a long shot, but thought I'd ask.

Just one question. Why is the top cap screw hole .003" further from the center than the other three? Typo?

Another option, check out the relatively new Street Demon carb http://www.demoncarbs.com/Types/Street%20Demon.asp

One of the best factory shaker scoop designs was on the '74 Pontiac Trans Am I owned back then. It originally had a factory-blocked opening but all it needed was drilling out three rivets for it to be fully-functional. In case of rain all I had to do was put the original factory plate back in...
