How much weight gain from adding a Dana and roll cage.

I'm going to say what weighs when I figure it out.
How much did your 69 weigh. I think those cars are heavier than a 70 to start off. But I know I'm adding extra weight and won't have any glass parts off the bat.

With my 330 in it and about 8 gallons of fuel( have a 15 gallon cell) it was 3360.
8 point MS cage, pro car seats, full carpet, headliner, door panels, dash etc, etc.
factory hood, bumpers, glass, etc.
