not to be a pessimist, but your motor cranks kind of funny

That engine has compression all over the place.. I can hear it based on the load on the starter.

Did you have the entire engine apart? Explain how you carried out cam timing.

[QUOTE=Jake Raby;380855]That engine has compression all over the place.. I can hear it based on the load on the starter.

I had the engine completely torn down for an IMS shaft replacement.

I locked the engine at TDC and timed both banks using a factory built timing tool and the instructions from the 987 manual

It has the original lifters in it.

Both banks were timed the same way, meaning engine locked at TDC and timing tool used.

The picture below shows bank 1-3 timing

Still worth a quick double check that your still in time.

pull the oil scavenge covers and make sure the cam sprockets didn't slip.

left and right bank do get timed 180 out of phase. Been a while since
I personally checked but the cam holder gets rotated such that
when timed both camshaft sides are slightly on the outside of the case.
Double check that as it's been a couple years since I did it myself.
