Yes, it is a 2.0 litre. It is from a 1978 Lancia Beta. Twin DCOE 45's is what makes the sound special. It makes around 175-180bhp.
Corse I
I got some front damper mount plates made to drop the top mount by 1" as the front trailing arm was only about 1/4" from the chassis rail and on bump was hitting it. If I jacked the spring collars then I had no droop. Now I have about 2" bumps and 1'1/2" droop and it feels good.
I have just had it set on one of those new fangled laser jigs.
I have got all the settings pretty close to those in the Corse I build manual, however:-
I started with caster FL 2"35' FR 3"31'
To increase these towards the Corse I suggestion of 3"-5" the trailing arms had to be wound out to lengthen them and now both L&R are 4"30' BUT the lower rear wishbone arms are now very much to the rear of the little tunnel they sit in just in front of the bulkhead.
Lengthening the trailing arms to increase caster does not tie up with what Craig says above when he says "wind it in", which implies shortening the trailing arm.
Am I doing something wrong?
Am I missing something?

Extending the front trailing links reduces the castor unless your upright was already leaning forwards (negative castor) rather than backwards (positive castor).
From what you describe then it sounds like your Track Control Arm is leaning back too far and that the top ball joint is actually farther forwards than the lower ball joint?
The image below was pulled from the www for the image but some of the text is relevant as well, just disregard the bit about power steering.

Thanks
That is what is "visually" looks like, but how can that happen?
There is no adjustment in the top ball joint position.
If I had to lengthen the trailing arm to increase caster, should the machine be recording it a Negative caster?
PS when do you want me to drive down
I have just gone and wound the trailing arms in so the bottom wishbone arms are now towards the front of the tunnel.
Looking down on the top ball joint the bottom joint is now in front - positive caster.
Amazing how only a couple of inches of adjustment makes such a difference.
More annoyed the machine did not pick up Negative!

Thanks
That was the photo on the right I was looking for to describe the tunnel
