Edelbrock aluminum heads

You guys and your spinning just don’t know how to set up a car chassis. My son took me for a ride in his 1970 duster with a stock stock crank in it. 3200 pounds (3450 with me in for a ride) 727 transmission with 5600 stall converter. 8 3/4 with 4:10 gears. It runs 6.54 which is around a 10.30 quarter mile time. He runs a street legal 10 inch drag radial on a 10 inch wheel. After we drove around he stopped on the return road and jumped on it. He scared the Ba-jebies out of me. That car hooked and booked with zero heating of the tires. Simple caltracks with mono springs and Rancho shock with sliders. 90/10 cheap front shocks. Not everyone spins like driving on banana peels.
