Cyl Mass to be Delivered

[JWM_Jankowitz]

Just want to ask if it is important to keep these parameters standard or should I start with setting all 8 cyl to 1.0
Why are they different on some cyl from the factory?

I beleive that table is to adjust for cylinder to cylinder a/f distribution.

How would you know what to change unless you had a wideband in each exhaust runner?

Good point... and I agree. I saw that they are different for various 392's and was wondering if there is a way to tune that or just leave it at a standard value of sorts

I would only change them if you are swapping manifolds such as going to a PD blower

Ok, thanks. It is odd that some is left at 1 and some as ever so slightly above 1.
