Jetting foe Edelbrock 1406 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BobbyK · 05-16-2008, 04:49 AM

Bought a used Edelbrock 1406 from a guy in Colorado,elevation 6500ft.
My elevation is about 600ft above sea level,Ontario,Canada

He had it jetted and working well for his elevation.

Just wondering where I should start as far as jets go.

Carb is not for my Blazer it's for a future project.

If he gave you the original jets/rods/springs that came in it new, I'd put those back in it. If not, try to find a manual and use the tuning info in the back. I wouldn't hesitate to get the calibration kit, it has a large selection of jets/rods/springs and you can get it dialed in pretty quickly once you have it installed and running.

Heres some quick specs for the 1406 - main jet .098 - metering rod .075 x .047 - rear jet .095 - step up spring = yellow.

Thanks boys,
I do have the owners manual and was also looking at the one on Edelbrocks site after I had posted.Some great info. there.

I havn't torn into the carb yet so I don't know what jets are in there.I'm sure they are alot leaner than I need.

Unfortunately he did not send the stock jets etc.

Do the colors of the springs fade?
I tore the carb apart to get the jet #'s(hard to see BTW) and the step-up spring is the natural steel color no hint of the stock set-up yellow.

The main and secondaries jets were the stock .098(main) and .095(secondary)

Metering rod was also stock with a # 7547 stamped on it.

Here are a couple pic's.
Pretty clean unit.

Here's the metering rod.

Main jet,really hard to read the numbers.I used a magnafying glass to decode the numbers.

Secondary jet.

[QUOTE=BobbyK;2724447]Do the colors of the springs fade?

Yes. And they can also lose their temper over time and compression. A new spring kit, p/n EDL 350- 1464 [multiple colors] would give you fresh springs and tuning options for $8 at Jegs.
