Opinions for an intake/carb combo

Takt · Aug 31, 2010

I had my motor rebuilt to a 348 stroker over the winter. I was/am stubborn as I have a high rise dual quad setup on it and wanted to keep that.

After driving it for the season, I've started to waiver on the setup and then this morning I mention to my wife that I'm thinking about changing the intake setup and she said, "Good, never liked that hood scoop sticking out." Hmmm ... pretty good wife since she's never mentioned that before

Since I don't have the coin to actually put a blower on the motor (which is what I'll want ultimately)...

What intake/carb would you suggest for performance + looks at shows?

Motor Specs:
348 stroker bored .040 over
10.2:1 compression
2.02/1.6
Aluminum heads, hyp pistons, cast steel crank, forged I beam rods .480 lift cam

I'm looking into a GT350 hood scoop to cover the big ass hole in my hood now ... HAHA

Also - suggestions on where to get the carb/intake ... and even the hood scoop.

Thanks!

I like the idea of the GT350 scoop. I thought about doing that to mine. Before you decide on an intake and carb setup, you should consider how you drive/use the car.

I have the Edelbrock air gap dual quad on my 68 Cougar. If I were going to do it again, I'd look real hard at putting the blue thunder re-pop on the car instead. (the Edelbrock dual quad set up will only fit the Edelbrock air cleaner) The biggest reason is that, I prefer Holley carbs, and I would rather have the Cougar scripted dual quad air cleaner on it. Take a look in my photo bucket page, and you can see how my set up turned out. I have a 'glass hood with the GT-E scoop molded in, so clearance for me wasn't an issue. I "think" the air gap will clear a steel hood, with out the insulation.

In retrospect, I would rather have spent the few extra bucks upfront.
The Edelbrock dual quad performs well, I will admit that probably my tuning is what's causing any 'poor' performance.
I have a pair of Edelbrock heads to install when I get back from Africa, and will do some more dialing in after that swap...I've just been dreading the whole valvetrain geometry stuff all over again. Even if the Edelbrock heads use the stock locations...

On a 348, id do a Victor Jr. and ditch the dual carbs.

Takt · Sep 1, 2010

I am dumping the dual quads ... going to single carb with the GT350 scoop on it. What should I run as the single carb?

Thanks

More info on cam and heads?

Takt · Sep 1, 2010

I'm not a true car guy, just learning. But here is what I read off the build sheet.

Cam is a Erson E212024 Hyd campshaft. Intake @ cam .305 @ valv.488. Exhaust @ cam .305 @ valv.488

Cam timing is .005 lift. Intake opens 36 BTDC exhaust 76 bbdc and closes 68 abdc 28 atdc

Heads are Strikeforce alum heads.

No idea if that is what you were asking for?

I'm no expert either but here are my thoughts:

Initially I would've said Vic Jr because of the c/r and engine size, and considering you had a dual quad, this would be have much more torque.

RPM Range 1000 - 5500
Duration @ .050 Lift 218/218 deg int/exh
Adv. Duration 284/284
Valve Lift .488/.488 int/exh
Lobe Separation 110 deg

But after seeing the cam specs I changed my mind. I think you would be much better suited with a RPM air-gap. Your cam is a smaller cam for the displacement & c/r so using a vic jr would cost you a lot of torque down low that you wont make up on top end.

Victor Jr RPM Range: 3500-8000
Victor Air-Gap RPM Range: 1500-6500

Its all about the entire combo complimenting each other. Go with the air-gap and don't look back, you'll be very happy with it.

Wicked65 · Sep 1, 2010

Well, really, after looking at the cam, ect. The Air Gap probably would be a better choice. With just a off the shelf 650 Quick Fuel Technologies Carb. Call Alex at Money Maker Racing, ( see sig) tell him Greg in California Sent you.

Too bad you're off multiple carbs. This setup fits under the stock flat hood and works extremely well, and the 'holy crap' factor upon opening the hood doesn't hurt, either.

tx65coupe · Sep 2, 2010

Thats cool. I've never seen a Ford small block with a six pack before?

As you want to get off the dual quad deal, and you want true performance, then get a custom built carb matched to your engine build. Gather your engine build specs and where you want to make the power, and contact Patrick at ProSytems. He will build a carb for your engine that will work "out of the box". It ain't cheap, but, if your are serious about performance, then the cost doesn't matter.
My AFR curve was pretty much "spot on" fro 2500 to 6200.
Happy Motoring!

Mark me down for the Edelbrock RPM Air Gap too. Even bigger engines than yours are using this intake just because of the gains down low in torque. Im not a huge fan of the Vic. Junior on street motors, but if you were going drag, or had a bigger more aggresive cam I may recommend it.

Times two. This is what I've had on the 331 in my 77 Comet ever since I built the motor 6 years ago (had the motor in my 89 Ranger too) Dead reliable, runs fantastic, ain't touched the carbs since the initial tuning, other than a rejet after installing spacers under em. Always get compliments when the hood is lifted, many times they're speechless cause they don't know what multiple carbs is.

It's cool to think you used to be able to walk into your local Ford dealer and buy a complete tri-power setup off the shelf!

You can still buy em from Mustangs Unlimited. Brand spankin new. Gonna cost you a bit more than it did in the 60's though. I bought my set second hand for $1100 (shipping included) from a guy in Indiana. The whole set was only a year old when I bought it 6 years ago.

2+2GT · Sep 10, 2010

Hmmm… By my reckoning, the $1100 you paid is less than the inflation-adjusted $1500 original cost, so you did well.

Too bad Mustangs Unlimited did not have any on display. I was in there today picking up a new ring and pinion set to swap with out the original 2.80 set.
