Thread: Is 3/4" ok?

Tweet

You never get too old to see something new. I have always known that you could offset an engine by 1" or 2" in the frame for added steering box clearance.
Likewise, I have always known that some rearends do not have the pinion shaft equally spaced between the backing plates.
I never thought too much about this stuff, and the cars I build have always had everything pretty much on center (I'm a maniac for symmetry).
This past summer, I seen a 30's era pickup truck hotrodded, and the motor was offset towards the passenger side of the truck about 1 1/2" for steering box clearance, while the pinion shaft was offset about 2" towards the drivers side of the rearend. ( I think it was a Ford 9" but I could be wrong).
The truck was channeled, with dropped floors, and the guy who built it had actually built the transmission/driveshaft tunnel in the floorboards running at a quite pronounced angle from the front of the cab to the rear of the cab, to accomodate the driveshaft. With the seat in place, it really wasn't all that visible, and the fellow said that the truck performed very well, with no vibration or weird handling characteristics.

As long as the rear axle is perpendicular to the chassis and the crankshaft is parallel with it, you can offset up/down/left/right.

This doesn't sound like it would work good with high horse power engines,not talking about circle track.The up and down ,no problem,but side to side ,I don't think so.Is the engine in a Vette off set also?

Whether or not it sounds like it will work, it will. It's been done for years on street rods and other high performance cars.

As Henry said, as long as the rear exle is perp to the body/frame of the vehicle, there will be no problem. if you think about it, the only thing that is different is the location of the motor, everything else functions normally. The driveshaft still goes to the same place, set in the same position. The motor is still parallel with the body/frame as well, it is just not symmetrical on the same plane.

BigTruckDriver, I can see that you're gonna take a lot of convincing......
