That is the major drawback to sidedrafts, mucho $$$

I had to buy my carbs used & pieced together a complete system.

I lucked out & bought carbs & A Datsun intake for $200. Then I bought the intake & linkage new.

Search swap meets, craigslist etc.

Here are some examples:

With this intake set-up it is by far,,,, I say , by far the best intake set-up you can run on a 6 cyl, other than maybe a custom set-up.

I am talking from experience & if anyone says different, then those people have never tried them.IMO. \:D
If I would have known then what I know now, I would have never ever messed with 2 bbls or 4 barrel carbs. Clifford & Offy intakes.
I should have went straight to a side draft intake from the get go.

It is really worth it.
