Re: Why such a weight difference?

I was told that a big block th400 combo works out to be close to the same weight as a small block th350 combo with all the AC stuff....

That don't make sense. The TH400 weighs about 15-20 lbs more than the TH350. Small blocks weigh about 150-175 lbs less than big blocks. All the air conditioning equipment doesn't add up to 200 lbs unless I'm forgetting something.

its about 120-160 lbs for the AC

dont forget all the AC/Heater vents and- the heater core is about 25 pounds alone

No that's still in there...... it is isn't it black? I'm just talking AC components only.

i removed all heater components, had no ac from factory, so my switch panel i made goes in the hole in the dash for the climate control was. and if you just start taking things apart the factory over does it with the bolts on a few things i have about 5 pounds of bolts i took off, quite a bit for small bolts.
also the big metal bar in the doors is 85 pounds (or so i was told by another g3 owner) that also will eliminate sagging doors and if you have no radio like me take out the speakers and ALL wiring for it, also the door buzzer and seat belt alarm wiring and that will also clean up the wiring.
the dash is one that is over bolted in mine was at least. also sink in the bumper, and get lighter suspension parts of course like control arms, springs and a lighter transmission crossmember. trim is heavy when combined mainly the emblums and on the door sides and bottom chrome. hood pins with locks so you can remove the pull system inside and the whole latch system under the hood, smooth out everything you paint by using a grinder like the frame i took about 1/8" off my frame in the engine compartment after i cleaned it, it takes a long time but its smooth and shiney and the big chunks of steel are gone, jegs.com sells aluminum transmission tunnels for around $80 big weight difference, wheel tubs that are lightweight, fiberglass, and lexan for the windows or 1/4 side windows at least, the factory brake system is heavy too get lighter calipers and rotors, remove the factory insulation its cardboard and tons of crap insulation and get some dynamat.
lots more too.
