My Wescott bodied 32 highboy roadster with 462" Buick weighed 2400# on the NHRA scale at March Meet a few years back.

Not too bad when you consider the added weight of the T-400 over the T-350, four point 2 1/2" x .120 wall roll bar and cloth top.

Fwiw, the 400, 430 & 455 Buicks weigh only 15# more than an SBC if you swap the 70#+ intake manifold for an aluminum one - which I did.

Most 32 highboy roadster's are reputed to come in at 2300#.
These cars run the usual 350, T-350, 9" combo.
(I've seen two of these highboys run about 112 mph in the mid-high 12s in street trim, mild SBC's and slicks. One of them was a mildly built 327.)

Doing a little reasonable extrapolation it looks like my Brookville bodied 31 on 32 rails project highboy roadster will come in at 2200#.
I'm not being overly weight conscious like the drag race troops, but I ain't getting crazy with the heavy stuff either.
It'll also be powered by a 462" Buick and if things work out right a pair of Edelbrock aluminum heads.
Not sure about a top on this one, maybe later, that ol' Arizona desert sun can get to you pretty fast.

It gets a 4 point roll bar as well.

One thing to keep in mind about farm scales and the like, they don't seem to weigh very accurately at the lower ranges.

Best bet is to weigh one corner of the car at a time on a 1000# capacity balance scale.
Add the weights and you should be within a couple of pounds as well as knowing which corner of the car weighs the most.
Be sure and make three leveling blocks of scale height so the car sits level on the scales.

A guesstimate for sure, but it looks like there's about 1400# on the front of my 32 and 1000# on the rear.
Probably why it spins the tires so easy.
Not that 520-530# of torque has anything to do with it....
