I'm needing to build a box on top of a dolly to sit a 3400 engine in for transport. I'll use 2x4's standing them up to make a 4" deep cradle box for the engine to sit in. I don't have access to an engine to measure the oil pan. So, I've no idea the size box to build.
If anyone happens to know the how long and wide the oil pan is on one, please let me know.

It is best to go to someone who has the same car and measure it, if you do not want it, it can also be in the car's manual because this is what it should be, or a car that has for sale, you can also ask

Exactly do the best as the colleague wrote above, it is best to drive to someone who has the same car
