Good or bad, or should I just leave it be? I have an adjustable timing chain set up, just for kicks would it give the engine more low end power if I advance the Steeda 19 by 2 or 4 degrees. Im bored and feel like experimenting.
Should I advance the cam timing on Steeda cam?

I would personally not play with it unless you're going to degree it, thats when your going to get optimal results.

A lot of aftermarket cams have some degree if advance built into the grind.
I would call steeda and ask the tech line for your cam.
Odds are going straight up dot to dot is all you will need to do.

I couldn't give you a definitive answer to your Q but my thoughts are 
A rule of thumb is ................
advance for low end and retard for the high end of the power range
Another rule of thumb is ...............
2 degrees will be a fairly subtle if noticable at all kinda difference
from the things I've seen in the past
IIRC
seems like you see alot of crank keyways done with 4 degree variations
With the #19 cam, a bit of advance just might be a good thing
but I'd want to get some advice from someone who is more qualified than
me ... thats for sure

Since your in the mood to goof around, then why not... Thumper told me I should advance mine 2 deg's when installed...I went straight up though... The 19 is kinda lazy til around 2800...Moving it down some would be a good thing. I added 373 to help some.. If opening it up again I'd move mine..
I would check the PV for sure...I had plenty of room on both I & E and my heads were milled some.

I've even pondered 4:10s.

I may try this, I am putting a 19 in my car. Why would you need to check PTVC? Does advancing it chage the (for lack of a better term) geometry of the valves and cam?
Poboys let me know how it works out for you. I could uses a little more lowend due to the AODE
Retarding the camshaft will open the exhaust valve earlier, and the intake valve later. This will increase clearances on the intake side, but decrease them by the same amount on the exhaust side.

So yes, you will need to check PTV clearances when playing with the camshaft timing. You want minimum clearance (rule of thumb) to be .08" on the intake and .1" on the exhaust.

I went with 6.300s for the same reason.
If anyone cares, the stock pushrods weren't long enough for my (stock) pedestal-mounts with the new cam.
