Yeah, I was pretty surprised by that too. I guess it's because the battery is in the trunk.

What does a Optima Red Top weigh? I'll do a quick calculation and see what that would've done to the ratio.

Optima Red Top weighs 40 lbs according to this

Adding a couple pounds for cables and the battery box then if the battery was in the front it would be :

Front 53.6%
Rear 46.4%

It's a 383 with iron vortecs.

Pretty much everything except what I previously mentioned is stock.

has inner fenders
has new repop bumpers
all steel body panels including steel 2" cowl hood
has power steering
has front bench seat (for now)
rear seat still installed
has a spare in the trunk (but no jack)
no radio or speakers
has headers (I think they are lighter than exhaust manifolds)
I'm not sure what the wheels are made of but they are Cragar Street Stars
185/60/15's up front 245/6015's in rear
subframe connectors add a few ounds

That pretty much covers everything

I've read many times that moving your battery to the trunk has the same effect of weight distrubition as moving your motor back several inches (I've actually read a few that said "up to ten inches back")...these results would sorta support what those magazine articles stated...

Very cool...

I've read (hey, must be true right?!?!) that when placing the battery as far back as possible in the trunk (behind passenger side tire), it has the same effect as adding TWO batteries right over the tire due to the lever effect.

thats not quite right....your missing the effect that leverage would have on the overal weight balance....Normally the battery is right near the very front of the car....when you move it to the trunk you have moved that weight at least 12-13 feet from its original location...that will make a big difference...

Just look at it this way...pick up your battery and hold it... that took 40 lbs worth of force...now pick it up and hold it straight out at arms length in front of your body...that takes more than 40 lbs worth of force to do that....NOW try picking that battery up on the end of a 12 foot pole.... ....I gurantee it will take WAY more than 40-50lbs worth of force to pick that thing up....that is roughly the effect it has on your car when you move it to the trunk....

not quite a 12 foot pole since the center of gravity is somewhere in the middle, but we got the gist of it.

i wonder what my nova weighs. on the old rod knockin' motor i hit the brakes way before i crossed the line and i ran a 14.4 at 100mph at 3000 altitude at LACR.

my car has very little in it, no fenderwells, no power brakes, no power steering (chopped the pump off), aluminum intake, missing lots of upholstery, and cross-drilled floorpans (oops, was that rust?)

Absolutely....that is why I said "roughly the effect"
