Default 1800% more horsepower than stock……...Hellcat Killer

In a straight line, at least!
This is an engine/chassis swap on my 1970 Daihatsu HiJet Micro Truck. The truck measures 4 ft wide by 9 ft long and will fit in the bed of a Ford F150



Before:
It was originally powered by a 22 hp 360cc two stroke water cooled two cylinder engine.



After:
It is now powered by a 400 hp ZZ5 crate V8.



I swapped the chassis with one from a Jeep Dj5 (postal). It is two wheel drive with a limited slip Dana 44 rear axle. The frame is shortened and the back half is narrowed. Both the front and rear axles are also narrowed.

Both frame rails were full of acorns when I separated the two halves!







Here is the narrowed shortened frame, now fully boxed as well





The truck is being built up using an old low-perf 307 2bbl that I keep around the shop for builds. It is immune to the sparks and grit. The motor is mid-mounted and utilizes only a clutch, there is no transmission. I want this to be a sleeper, so I am maintaining the stock wheelbase and overall dimensions. That said, with a 66" wheelbase, there just isn't room for a whole lot. The engine is too tall to fit under the cab. With a power to weight ratio of less than 5 lbs per horsepower, a transmission isn't necessary. The truck will use an electric reverse, photos to come.



The One Speed is made up of a bell housing and a slice from a saginaw transmission.

The engine, clutch and rear axle are used as a unit and all ride in this cradle which also acts as a ladder bar setup. The front pivot mounts to the frame directly above the front axle. The rear leaf springs attach to the rear axle in their normal position.



The electric reverse consists of a late model Ford Taurus flex plate and starter. It will mount in this area









The mule motor and exhaust are in place



Built a custom aluminum gas tank. My friend William tig'd it together for me.



Had to move the steering column to the right so that I could get my leg in enough to close the door!



Fitted some gauges. No transmission means no speedometer output. Being direct drive, there is a correlation between the rpm and the mph. As it turns out, the speed is exactly double the rpm. When the tach reads 20 the speed of the truck is 40 mph



Running with the 307



At this point, the 307 is out and the 350 is going in. Hope to fire it up this weekend!
