The prev 455, did it have E heads & headers? No radio, alum rear drums? Do you have a copy of the '70 AMA sheet where it lists weights? I would have bet another 120-140 lbs.

Roger, attached is the AMA weights for the 1970 A-bodies and the associated weights for my Tempest…
Coupe 23327 3336 lbs.
Turbo H-M (400) 23 lbs.
400 V-8 4-bbl. Engine 245 lbs.
Power Steering 31 lbs.
Power Brakes (Drum Frt.) 9 lbs.
Radio 8 lbs.
Add for 12-Bolt Rear Axle 15 lbs.
Total Estimated AMA Weight 3667 lbs.
Previous Owner Weight 225 lbs.
Total Race Weight 3892 lbs.
Remove 75 lb. driver difference (75 lbs.)
My Race Weight 3817 lbs.
The previous owner ran without the spare and jack, so add another 60 lbs. to his scaled weight of 3680 lbs. = 3740 lbs. with him and a half tank…3801 lbs. with a spare and full tank of gas. Remove my 75 lbs. difference and that equals 3726 lbs. with me behind the wheel with spare and a full tank. So, that probably looks a bit more plausible. Take off the power steering (31 lbs.), half tank of gas (61 lbs.), and the spare/jack (60 lbs.) and the weight drops 152 lbs. to 3574 lbs. (3665 lbs. based on the AMA weights for a 91 lb. discrepancy). I probably made this a lot more confusing than it has to be, but that’s my math and we’ll see next year.
