A body top speed

'76 Scamp, 360 with cam and bolt ons, A833OD in 4th, 2.76 gear, 26" tires, 4200rpm on the tack, Says it's 140give or take. The car had stock everything and needed all three traffic lanes to get around bends.. But it did it. I've had A, E, and C body cars past 130, a couple past 150. Someday I'll have to get one to an actual race track...lol.
