Old Yeller vs Drag Truck "2021"

I've been looking at these.... keep teasing myself "Drag Truck II" ????
Should drop a full second with weight and wind factors. That'd put me at 7.2's in the 1/8. Need 6.9's to go 10's. Most I have been looking at are cheap due to a blown Mitsubishi. Just swap the drive train :)

Neat little trucks, and I heard that the automatic D50s had 904s. Never knew that.
