Holley smog carb

I have just recieved a free carb, it needs a rebuild but its still free.
The problem is its a Holley # 6210-03 according to the number on the airhorn.
A 650cfm smog carb...

My question is weither or not it would be worth my time to rebuild it or if I should just put it back on the shelf?
What makes it a smog carb?

Its a spread bore carb...

650 cfm is about what I need. I'm just not sure if a smog carb is worth the trouble?

Re: Holley smog carb

Typically smog carbs have a different base than non smog with more vacuum ports.
The carb you have shows up as a 650CFM 327-402 ci engines. It makes no mention of smog in my Holley Book.

Re: Holley smog carb

Thanks for the info.
It does have like 6 vacuum ports.
The number 6210 is currently listed as a 650cfm smog, so I assumed this was the same.
I guess I will rebuild it and give it a try.

Re: Holley smog carb

I have that carb on my 383, and I like it.
Seems to be pretty good on gas when I keep my foot out of it.

It was a Holley replacement for the original and came with my car when I bought it.
I originally planned to use something else, but decided to give it a go and see how it worked out.

My motor is an all forged bottom end with 6 inch rods, 10.25 CR.
Lunati Voodoo 60103,
Eddy Performer RPM heads, and Air Gap intake.
Pertonix Flame Thrower Dist.
TH350 with 2k stall, 3.08 rear gears.

This car is only street driven, with some tweaking like gears and an OD trans it could do better but overall I'm pleased.

Some day I will do some upgrades, right now I'm paying my son's college tuition, So it will be a while.

She runs pretty nice on pump gas too!
