Gas mileage saga continues (Sorry, QUITE LONG)

[Marteney, Steven J.]

Well, I responded to this email over the weekend and realized I never saw it
hit the list.  I've adjusted my equations for the square root thing and it
slightly raised the calculated AFRs to between 12.0 and 12.5:1.

To answer the cam question, the cam is the ZZ3, 208/221 at 050 w/ 0.484 and
0.510 lift, 112 lsa.  Not radical at all.

Steve

I think the increase in fuel delivery is the square root of the increase in 
fuel pressure.

1)22 lb/hr*SQR(48psi/43.5psi)=23.1lb/hr


Also,
possibility one for decreased MPG:  what's you lobe center on your cam?
Over 
scavenging maybe? (probably not)

Possibility two:  Laying into the gas a little more while having fun with 
your new headers? (much more likely!)
