|
|
I know there are several kits on the market to fit the dual carbs on the 40 HP, hence I would love to make a list here of all of them including prices, with all of your help...
..as well as what adaptation are possible out of the single port ones...
..or starting with junkyard 40HP intakes, duely modified... |

You mean old-school ones? Because I've not seen any new dual carb kits for for the 1200 - 40HP SAE. There was someone that was making manifolds, but I don't know what ever became of that.
The only way I know of to do it with parts available now, is to buy 1300SP heads and put them on the 40HP jugs, and then use SP dual carb kits. Or you can get european 1300 DP heads and do the same. |

Pretty simple to make a dual carb kit for almost any application. I did it with a 40hp on a dune buggy I built a couple years back, it used two 28/30PICT carbs.
You need the lower (head) flange from the 40hp, cut maybe a couple inches above the flange, some appropriate pipe (sectioning the VW intake works fine) and two manifold to carb flanges. The good thing is the 40hp manifolds are cheap/free most of the time, so all you need is a welder, some beer and a free saturday afternoon.
You mock it up on your longblock, spot weld and finish the manifolds. In my case I heated the manifolds and slightly 'bent' one to get correct offset. I made linkage hidden on the front of the shroud using steel rod I bought at the hardware store and random dual carb linkage pieces. If you've seen many of the old kits you can easily picture how to make it, and it seriously works fine, many times better than the old stuff.
Vintage is always cooler, but even with a decent wallet they can be hard to find. _________________

The earliest T3's were single side draft of course, so the 13/1500 single port dual manifolds is what you'd start with. They have a different flange where the manifold bolts to the head, but you could saw that off and weld 40hp manifold flanges on...that would be pretty simple.
I personally never liked the Solex's that came on T3's (pcib?), and I dont know if 30pict carbs have the same size base..don't think so. But just another detail in the process. _________________

I'm making 2 sets. I'm just cutting up the og manifolds to use. One set will have the pci's mounted sideways with a crankbell linkage. The other will have Weber or Berg linkage and the carbs mounted the traditional way.

I will.
I haven't decided yet. That will probably be one of the last things I'll do before the engine is complete. I'm going to build the engine over the winter and I'm hoping to have everything done by April of '09. _________________ www.DenverWildlifeControl.com |

No, not that I know of. As I mentioned before, the only way to get something like that, is to get like Weber 34ICTs for SP and use 1300 heads. |

I wonder if Baby Dellorto's (34's) would be too much for a 40 hp? I have some with dp intakes....so I'll need to buy (or fab up) some single port manifolds.
