It was always a Hemi and Lenco till it was sold less engine and trans to the Northwest.
Milodon Hemi installed by Gary Emig in KC.
Mostly B/FX, some Pro at local division tracks and then Pro Gas.
There is a rumor of it running in the eights.
Would have been high 8's.
I do know it went 149 miles and hour.
I know they ran a 426, a 396 and a 366 hemi at one time.
The 366 was not a good engine.
The 396 was built by Gary Ostrich in Colorado.
