Maybe im too cautious

Yes I am beginning to think so, you shouldn't really let it idle at all with a new cam in it, you can scrap it quite quickly if you don't follow the running in procedure.

Trying to remember the oil ways in a V8, but one will get oil before the other for sure. I honestly think bring it up to 2500 and hold it for a while and it will get better, I know mine have done this for me after rebuild. It sounds quite sweet in all honesty, hard to hear it is misfiring....

when i started the engine, strangeley it only ran on 4 cylinders from one set of coils

i swapped the coil for the other and strangeley it was the same cylionders firing and not the opposite ones

ruling out the coils.

So, very basic question: Have you got +12v to the plug for the non-working coil bank?

Yes

I have also had the noid tester flashing away on the cylinders and also the inline led spark testers.

But as Mr Noisy has pionted out, are they doing it at the right time?

How do i check this out?

Get the cam run in and then worry about it, then you won't scrap the cam and followers and have to pull it all apart again.

To check they are firing in the right order, you just need to check your wiring in all honesty, ABCD from the EDIS and the associated plug numbers 6&1, 8&5, 4&7, 2&3.

Once you have the cam run in you can check the timing properly with a gun pointing at the pulley/timing marks and connected to either plug lead #1 or #6.

As long as you have the ABCD and plug wires in the right place, it will be fine.

The injectors are just bank fired (4 or even all 8 at once depending on setting) so they will make precious little difference to the running as 3 of the 4 are squirting at the back of a valve anyways.
