I tried that 680 battery. It's fine for a race car but if you have a street cat you need the next size up. Idleing at a stop light at night with the wipers goin, the radio goin and the heater fan will sap the power out of it in a heartbeat.

thats a trans am seat, they are heavier "TA Passenger seat leather with lumbar pump is 42lbs" The list on the 1st page doesn't say that, it should.

PC680 was fine another year, bigger cam now too. The battery starts the car, the alt. keeps it running, If your car stalls with it running, the alt.or something in the electrical system, or the tune sucks.

LS7...............107
RHS...............110
Dart Billet......128
6.0L Iron.......220
LSX...............230

These weights are quoted from here: http://www.yellowbullet.com/forum/sh...d.php?t=480958

I have weighed three LS1/LS6 blocks on different scales and all were 95-100lbs with the caps. So the 6.0 liter is more like 120lbs more.
