Quest for 7's in the 1/8

Amen the 727 is the king of course I mean it was behind anything from a half ton jeep truck 4wd to a large dual wheel motorhome but a 904 can be built easily to achieve 7,s in the 1/8 minus big sticky's and large converter in heavy vehicle.​
Eventually, if the 440 plan ends up in the truck, I wouldn't mind running the 904 behind it too
