I scaled my car today, was heavier than I thought! Challenger, It has a glass hood, glass front bumper aluminum brackets, no back seat. Does have a 10 point mild steel cage, Dana 60 and a Siamese mega block, full tank of gas. I was not in the car. But it was better front to back than I expected!

That is without you in it?
My 71 Charger is 3860 without me.
I only have a 6 point and full interior.

Any thoughts on what items are coming in heavier than than they should be?

I have no idea where the manufacturers got heir weight from but they all seem very low compared to actual weights. I almost had a stroke when I weighed my gremlin and it is going to be over 3200# with glass and no interior....

This happens quite regularly on built street/strip cars, they get heavy quick! Cage, safety equipment, heavy block, better cooling system, heavy duty trans with an added cooler, shield and gear vendors unit. Fuel system is heavier than stock, electrical system is heavier than stock, it all adds up!

Thats not bad with a cage, dana and aftermarket bb. My brothers 72 Cuda with a bb is 3650 with him in it. I bet the dana, cage and bb added 250lbs to your build.

As I remember my street Challenger (SB 4 speed) was right around 3600 w/o driver. The factory bumpers weigh nothing. Hood helps. The cage is probably at least 120#. A Mega block weighs around 75# more than a 440 block. You can always work on it. My 64 Belvedere comes in at 3130 w/o driver,full interior (-back seat), mega block, 2 batteries, Dana, all steel exc hood.

My 68 RR is 3780 Lbs with driver. 383 4 speed,Dana 60 & 8 point molly cage.

I forgot about the gear vendor, and trans cooler, electric fans, big fuel pump etc. it all adds up. I will start looking for places to remove weight, just started reading the thread on here lots of good info there.

2130# empty

My '73 Challenger w/ me on digi-scales was 3755 #s
- full OEM interior, except back seat
- 8-point rollbar
- OEM RB block
- glass T/A replica hood
- 8.75" diff
- only 1/4 tank of fuel when weighed
- driver probably 185 at the time, so car was about 3570

When it comes back out, it's going to be heavier, regardless
- Victor heads feel like 10 #s more each than Stage VIs
- swapped 8.75" for Strange S-60... 40+ #s?
- driver about 210 #s now
- and at 6 #s per gallon of fuel, an easy 70 #s for closer to a full tank

Add an est. 130 #s w/o driver and I'd expect 3700 #s for car -- assuming full tank -- and 3900+ w/ driver.

Nope, NOT light.

I did mild steel chassis on a 70' challenger, rectangle frame rails, dana 60, iron low deck and 906 iron heads. Without me in it was 2450lbs.

My cuda was 3780 lbs w/ me (320 lbs) in it and NO fuel. Had just backed it off the chassis dyno and the fuel pump was sucking air.
This was before I added all the nitrous crap onto it.

'70 cuda, all steel except for the fiberglass hood, 10 point MS cage, manual steering and brakes, no heater box, FULL factory interior (front buckets and back seat, all door panels, etc.), all aluminum hemi, 727, Dana 60, etc.
FWIW...my all aluminum hemi weighed the same as the iron block/aluminum headed 440 it replaced.

That car must of had a bunch of really thin sheet metal on it
My current S/P (1970 Cuda) car is a all chrome moly tube chassis with coil over suspension front and rear, narrowed Dana 60 with 40 spline axles and spool with dual disc brake calipers on the rear with fibreglas doors, hood, rear deck lid and both bumpers with all Lexan windows except for the front windshield, it weighs right at 2490 Lbs. wet ready to race with out me in it using a 400 block with aluminum heads and no radiator

Street Car Problems!

Last time I weigh-in mine was 3180.8 point, glass hood, glass front bumper

The 64 is a "hefty" 3970 lbs all steel with a full cage and interior! But it still runs 9.80's @ 140

Indeed.

3430# with me in it. All steel except the hood. Still has stock front and rear seat, carpet, door panels, dash, and headliner.

My 68 Charger 3860 without me, 4050 with me.
