Intake choice I'll be dropping a stock 2005 6.0 w 317 heads into my 79 malibu. 80% strip 20% street, 750 carb, 3500 stall, 4.10 gears, TH350
Should I go dual or single plane?
Will I be losing too much low/mid range if I throw a single plane on a stock motor?
I'd like to go single so I dont have to sell and buy new, but I'm new to this and not sure how these engines react yet.
THANKS

If you absolutely have no intention of going bigger on the cam, then you could go dual plane, but when you say this vehicle is destined for 80% strip use, I can't help but think that a cam is in your near future. If I am right about that, then I would still get the Victor Jr. for that application.

And yes I do plan on upgrades in the future, I just want to start with a base and go from there. Looks like I'll be choosing the Vic jr.

I have Vic Jrs on my cammed 6.0 and 5.3 in my Camaro and TA, but the 5.3 going in my 94 GMC with no cam is getting a Performer, and if you do plan on a cam and just refuse to do one right now the Vic Jr will work fine, but it would like the dual plane better till you get a cam.

Well, no actually it isn't. Carbs pick up low end torque compared to EFI, even with a single plane (vc jr in this case)

For the carbureted tests, we used a Holley HP 950-cfm carburetor on Edelbrock's new single-plane Victor Jr. intake for rectangular-port heads, plus a programmable MSD box to run the ignition coils.
What did make us sit up and take notice was how well the Holley HP carb and Edelbrock Victor single-plane performed down low. It was only in the midrange that EFI surpassed the carb, particularly with the XER273 grind. Yet you could expect to pick up at least another five midrange numbers on a carbureted application by having these profiles custom-ground with a narrower, 109-degree LSA, which usually helps the midrange and picks up the numbers from the peak torque to peak power rpm points
