If you were accelerating it wasn't a problem.
First issue is that I bought a MSD alternator which starts charging at around 1600 RPM.
The tuner told me the alternator had to start charging from idle and up through the rev range for him to be able to tune the car properly.
The alternator in the pictures is the new one which is a Ford unit.
It looks like an easy swap but it took a lot of work.
The other thing the tuner wanted was to replace the wheel the accelerator cable attaches to with one that was a snail shape.
It was a hell of a job to get the design of the snail right, which was a little know how and some luck. Once made, I can't begin to tell you how hard it was to adapt the new wheel to the existing cradle with stops in new positions.
The purpose of this new wheel was ... I hope you understand what I'm trying to describe ... is that for around the first third of depressing the pedal the linkages would travel less than with the original wheel thus reducing the hunting.
After that first third of travel the wheel and the linkages would return to their original relationship.
After installing the new wheel, the accelerator cable was shortened by approximately 1 inch or 25 mm.
It still hunts a little sometimes but it has improved by 90% from where I started.
I don't know if I'm right, but I put my problem down to the Morrison Injection really being for "racing" and not so much for street.
I don't know a lot about cars, but when I saw the Morrison cross ram injection, I liked the look and bought it.
I never thought it would be so much trouble to
make the distributor post
set up the crank trigger
because the crank trigger adjustment was on the right hand side of the motor I made the triangle bracket to take the alternator on the left hand side adapting the bolt points to the water pump.
I made a vacuum block and installed it near the firewall with pick ups under each runner, running back to the vacuum block. You can see the runners in one of the pictures.
Any one of this issues wouldn't have been a problem but it just seemed like it was one thing after another.
I don't think I would have had any where the same work if I had bought a regular 8 stack system.
Regards Mando.

well, time will tell as I am in month 10 of waiting for a manifold... I have a good friend of mine who has designed and tuned a few of morrisions manifolds. With out him I would have done an 8 stack for sure. I have already wired the car for EFI via a megasquirt. We will be designing the entire motor around the morrision cross ram, the porting of the heads the cam profile to make it tune able (from what I am being told.) this will be the only FE morrision Cross ram in existence. I am very much looking forward to it. My friend has one in his Pantera and I need to say it is very impressive.
