:D Well, I am getting 22 MPG now in the city.. up 2 MPG... but it looks like I found one tidbid that helps explain stuff... My rear end was changed by a previous owner... the original rear was an open diff with drum breaks... what is on there right now are disc breaks in the rear. I've been messing with a calculator and my RPM's match a 3.73 rear end much better than the 3.23. I will confirm tomorrow, should be cause for celebration...

Well, I just took the car for a spin before school... The neighbors must think I'm crazy now, I punched it, slowed down for the curve and went to the first stop sign on the road. I got to that four way stop, proceded to turn around and did most of a donut and took off wheels spinning... LOL

With 3.23's in first I should have been doing 2500 RPM at 20 MPH and I was doing 3000 RPM at 20 MPH... so I plugged it in and it comes out to 3.95 rear end... which of course isn't real, taking into consideration slight inaccuracy on the Tach, I've got 3.73's... and I've heard a slight banging sound going around some corners, I am suspicious that what I mistook as wheel hop is actually a posi rear... We'll see when I jack the rear in the air this spring... I keep finding cool things on my car... I bought it for $6000 and it's got all these fun toys :D probably upwards of $1500 in mods...

What should I run in the 1/4 with Headers, Intake, Exhaust and 3.73's?
