b20 short runner manifold 1800

I'm trying to track down a good short runner manifold for my b20. I've got a pair of solex side draft carbs on the way, but as I'm new to the 1800 arena, I'm having a little trouble finding the manifold I need. I currently have good headers on it that I'd happily trade or partially trade for a good manifold.

The Volvo Penta uses a shorter intake. Check the photo i've posted in the image library.

I found this manifold the other day, and it might not be the one you need, but I sure would like someone to tell me what it is.

That would be an aluminum manifold for either dual SUs or dual Strombergs(sp?) (NT) 1800

John Parker has manifolds for the webber sidedraft carbs, $250, if I remember right the solex is the same bolt pattern.

Can you describe what you are looking for better.

I'd say he's looking for these:

Those are long runners, similar to the old R-Sport/VCS manifolds. I think he wants the Warneford manifold, which is much stubbier and all a single piece. I don't have a source, sorry.

Do the solex sidedraft carbs use the single piece short manifold or dual short manifolds like the one from kgtrimning.com? Can anyone point me in the right direction on this? I have only had the car a few months and still don't know too much about the specifics. Learn as you go, you know.

Thanks,

Gregory

I have the long and the shorter manifolds in stock. Maybe even one set of the
real short ones.

Either, really. The carb end just needs to mount to a DCOE style manifold. I say DCOE but I don't know who really started it - Weber DCOE's, Dellorto's, Solex's and even newer injection throttle bodies all use this common carb/manifold interface.

I have a short one with a cast bridge between the sides - but the bridge is solid (unlike the SU manifolds which have a small connection between the two sides to help even out the idle should the carbs get unbalanced). I doubt anyone ever uses the short ones for performance reasons (other than mistakenly) but instead for clearance reasons. They tuck the carbs in closer to the engine and as far as I know also tilt them upwards slightly. Long ones wouldn't fit in the nose of my PV, and based on comments here I gather the upward tilt helps the carbs clear the steering column on RHD cars.

I'm not sure about the fit on an 1800 with long straight style manifolds.

I found my short set on eBay (~$350 for it and a pair of DCOE 40's). AFAIK the short runners are tuned for an improbably high rpm for best resonance - I'm using them just for clearance in the front of the tapered PV engine compartment. The longer tubes on the longer manifolds bring the resonant frequency to a more reasonable level.

Warnerford manifolds were made in Australia (whatever that's worth). Someone told me (and I don't remember who) that they were made short in order to avoid interference issues when fitted to RHD cars.

I don't know if this is the case or not, and it's not very credible given that I can't remember anything specific.

Best,

That's correct... however, even the long manifolds need to be run with long air horns on the carbs for the resonance to come down to the ~6K rpm range, which requires hacking away the fender on any pushrod Volvo.

If you don't want to do that, there's no disadvantage to using the Warneford, except that it won't fit with certain headers.
