Heater Bypass Valve

[565bbchevy]

So I just pulled the 307 Olds from my 86' Regal which has a heater bypass valve mounted directly to the intake and since I will running AC and will be installing a SBC I will have no provisions to mount it on the intake so I am thinking a universal style vacuum operated in hose one should work and I am wondering what I should use,

These are what i have used on Chevrolets, since they don't make the OE style that I've found....

These will be a good alternative to the EXPENSIVE metal inline cutoff valves. They're not gold prices, but compared to the ones mentioned, they're like 30-60 bucks on average for the metal jobs.

Yep.

I found this one for a Ford, maybe an alternative to the plastic one?

That should work just fine. GM has one that looks very similar to that.

Just mount it in the front of the SBC intake.

Thats what that hole is there for.

What intake are you using that doesnt have that hole?

 

[69hurstolds]

I don't think any Chevy engine owner in their right mind wants that big assed Olds goober valve hanging off the FRONT of their engine. It's bad enough Olds uses it on the back. Besides, isn't the hole sizes smaller on the Chevy intake? Would it fit?

I must not be in my right mind then because I mounted it in the front hole of the intake. Heater hoses are very short so this is where I put mine. Don't even really notice it behind the alternator.
