Holley 3.8 4.1 buick v6 4bbl intake & valve covers

[79Poncho231]

I have a rare Holley N/A Buick V6 Aluminum Street Dominator intake with EGR Provisions (NOS) and matching set of Aluminum valve covers. I won't be using them and want someone who can. The intake from the last 2-3 years "used" on eBay run up to $400. I have NEVER found a NOS for sale besides this one. There is one now on eBay for $325, and the T-stat housing is pitted out. I know there isn't a huge demand for these. I will be posting soon a used Edelbrock Performer V6 intake as well. As i convert my 3.8 too a 4.1 4bbl setup. \

Pictures updated. Needs a good cleaning, been in storage.

Asking $500 OBO for the intake & $225 OBO for the valve covers.
Location: Southwest, MI. Payment: Cashier's check, Postal order, MoneyGram, or PayPal.

I sold a brand new one of these still in the original box with instruction sheet and installation kit earlier this year. Nice intake but they are designed to fit the earlier low port heads '75-'78.

I see. What did it bring? The Holley catalog i have for this mentions 1978 - 1981 maybe 1983 engines. I doubt it is for older. pre-78 was still Odd-fire IIRC?

The Holley 300-22 Street Dominator intake was designed before the cylinder head change in 1979. Unless there was a design change later in production I'm not aware of, it doesn't fit the 1979 & up heads. I know mine didn't because I placed an intake gasket on it and it didn't line up. The difference is the heads, not if it is odd or even fire. Only the Kenne Bell Number 1 and both Weiand street and race intake manifolds had a "middle design" that fit both early and later style heads. They could be ported for exact fit for either high or low ports but most people found it wasn't necessary.

Forgot to mention something. Did you notice the firing order cast into that intake?

I forgot about the Head design change in '79. A friend of mine pointed that out also. This particular one I never put on any of my 3.8s. Both of them are 1979 engines, although my '79, as noted in my signature, has '80 Turbo heads on it. Interesting yet confusing stuff. Scratching my head now why the Holley catalog says it'll work for the years i mentioned in my last reply.

I did. But never thought to look at my other ones to match it. Good eye! I will double check that and re-edit the ad if i find mistakes.
