Default Vehicle Weight

I used some ghetto engineering and weighed my car after conversion. Unfortunately, I don't have pre conversion numbers, but from what I've gathered its about 150lb difference from stock cast iron small block/th350.

1969 Camaro/Ls1/T56/12 bolt/baer disk in front/16" TT2's rest stock
Front 1709lbs 56.5%
Back 1316lbs 43.5%
Total 3025lbs

The wheels surprisingly added quite a bit of weight as did the mutli-leaf springs. makes wonder how light I could get it if I went back to lighter wheels, mono leaf, and took out and/or replace the seats.

Anyone else have numbers?

When I got my '91 240SX coupe it weighted 2840lbs with an estimated 10 gallons of gas in it and everything still on it. After I stripped the interior out and took the gas tank off of the car I got it down to 2240lbs. That included the 70lbs stock exhaust that was on the car as well. Hoping with the LS1 in the car that it will be around 2300 to 2400lbs before I start making up fiberglass panels to lighten it even more.

1670 lbs with no gas on my LS1 Lotus Seven replica.

Since I weighed it, I think I have lost a little more weight (big steel tank to small aluminum tank, a little less sheet metal. I'll lose some more weight soon by switching to lighter fenders. My goal is to be in the high 15xx.
