CT crossflow- manifold`s from England aren`t best maded rallyparts for SAAB. Casting is mostly porous and soft. Also adjustment between suctioncover and suctioncurves are mainly poor. To improve that, some welding and ”helicoil”- thread as well adjustment were necessary. Here hints how to do proper alignment.

As usual, some threads were broken because of too heavy tightening of the bolts in the past and poor casting quality of the CT manifolds.

How to be sure that you tight intake curves to right position against intake cover if the bolt holes are allready with so big tolerance ?
Conc C/T manifold.
To be frankly this manifold is one of the worsed manufactured ever made to V4. We tested it early 1970 and it gavedlower hp then 2 staying carburettores. 2 of the over manifold have beeen made with smaller diameter and the flow in this manifold is terrible.
More they leaked a lot and had a very bad casting. My advise is to use something else. Sorry ;-)
You are right Rolf. I like to tested it in any way because I have good memories of CT manifold (except poor casting quality). I also think It will be much better for 1,6 liter Saab V4 than Saab´s original Cross Flow because of shorter canals to the sylinder. Let see how the engine will work
