Hi
I still haven't come any futher with my project, but I have some comments and answers:
Headers
The pictures below is from when I began to reinstall the 4.6L engine to the car, with the headers and the zf-box, after having driven it with the 4.6
with the BW35 and standard manifold and pipes.

LHS
I have never driven the car or even startet the engine with the set up pictured. I got the 5.5L before finishing the installation an startet with that project instead.
Engine
The engine is exciting, and was bought from V8Development some while ago on ebay. I do not know the output, but it shoulf be more than 300bhp and 400-500nm I guess. It depends on the injection/carb setup. The camshaft is a Stealth which is said to have very good idle, excellent drive ability, moderate mid range, good bhp. I used to have a Piper 285 in the 4.6 and the idle was poor, very irritating with an auto.
ZF Gearbox
The rear mounts is done in the similar way that BBLongman used on his car som years ago. But in my case I do not need to increase the size of the tunnel. I'll take pictures when finished.

I have had much use of BBLongmans site when planning and doing this.
Radiator
When driving the 4.6 I used the original radiator, with oilcooler. It was ok, but got a little warm staning in queue in warm days. I then had the standard exhaust manifolds. I have now rebuildt the standard radiator using the original frame, but got it made to a 3 row. Still with the oilcooler. The company that did the job meant it should bi ok for the 5.5L too. The nordic climate includes some days warmer than 30 deg celcius.
