Current options for DCOE style intake manifolds

How important is the water jacket for those of us in colder climes (Boston)? I guess it just takes a bit longer warmup without jacket?

Curious: Is there a difference between “knock-off’ and “modeled after” when it comes to a copy? -KB

Anybody can take an existing manifold, cast it, measure it, machine it, drill it and reproduce it accurately.   Your only guarantee is the integrity/reputation of the seller, which you don't always get with an internet buy.

Depends, are you going to regularly run it at below freezing temperatures...? I can always start mine when it's cold, but I have never driven it in the dead of winter and carb icing is rare but does occur under the right conditions. I would not want the plumbing and would take my time and look out for the OEM manifolds, their not that rare.

Are the OEM manifolds Tii manifolds? In other words, will a Weber 40 DCOE fit a Tii intake?

 

thx

“ti” not “tii”,  yes the oem “ti” manifolds will fit the DCOE pattern.  You’ll find nearly every carb and most ITB’s share the same mounting pattern.

Yes not just the dcoe style of carbs but also many of the downdraft style share common mounting pattern. Now for some truly useless info this was due to a early NATO requirement to standardize parts during the rebuilding of European economy's.  This is what I've been told anyway a quick google check doesn't support or refute it.

Hi,

One other comment on manifolds. I have never bought a "new" manifold that did not require mating to either the carbs and/or the head ports, so the comments on the IE manifold would not alarm me. There is a difference between poor casting and the need to mate them, the latter is almost always the case. If the ports cannot be lined up at all or the flanges are not true is a different issue.

As previously commented on, having to match ports is a given but when the mounting holes are neither in the right location nor drilled straight, that's a problem, especially when trying to fit precision ITBs with a 3 piece fuel rail that, trust me, needs to be absolutely straight.
