I'm going to dyno my truck on the 16th with similar mods to what you are thinking. 5x0.018 injectors and a 66/74/14. Ill post what it lays down.
Lol, not keeping me up, I'm at work, and trolling 10 different forums is all thats keeping me awake. And I'm happy to offer my little bit of knowledge to anyone who'll take it.
Mark TDC turning the motor both ways, and the middle of those 2 marks is True TDC.
See if the pin is showing in the pump, it should be if you are still at stock timing.
Going clockwise, mark where you want your new timing.
Remove pump gear.
Turn engine back so new timing mark is at the top.
Make sure pin in pump is still showing.
Put pump gear back on.
Double check timing to make sure it's where you want it (not necessary, but good insurance)
If my mind can put this all together right now, the formula is
(Dampener diameter*3.14159)/360*=how many inches in one degree of timing
So if you want to advance 8* of timing, mulitply it by the answer to the above formula
EDIT: wait for someone else to verify my post. I really might have forgotten something lol

But I have moved to a smaller turbo gt4202 and it spools much better.
I ran a 64/71/14 and now I have a 66/74/14. The 64 spooled a hair quicker but didn't seem to pull as hard as the 66 I'm running now. 66 is a little more smokey around town. I'm pulling off my AFC this weekend for some tuning and adjustments and bumping timing from 20 to 24. I'll report back to see how it's doing on the street..
Madmikeismad, that's how I time all the trucks I do. It's easier than pulling the Dv and lines etc. Plus once you mark the balancer for tdc you never really have to check again. This makes for adjusting the timing a couple degrees forward or back much much easier.
And on edit, box stock S366sx's (66/73-.91 t4) are $680 shipped.

Your welcome
With a marmon flange on the exhaust they sure are. You will need to have it machined if you want to use the common hx40 flange.
Or get a marmon flange from aiflo and weld it onto a down pipe.
Well I ran a 76/85 24 as a single for a while. I raced a friend with a 64/71 and he pulled like a mofo till my turbo spooled lol. But I have moved to a smaller turbo gt4202 and it spools much better. Being at sea level rocks
