'70 road runner, 528 Hemi, 727 with a tight motorhome converter, 3.23 suregrip. Stock intake, stock carbs, TTI headers.

10:1 compression with stock iron heads & an itty-bitty solid flat tappet cam.

Its tame & I wouldn't change a thing.

12's in the quarter on the reproduction F60-15's and 13 mpg no problem.
