It should work well.
350 and up to
400
No. The 400 is externally balanced, the 350 is internally balanced.
350 to 400 million dollars
350 heads will bolt to the 400 block. They will need to be drilled for the "steam ports" in the 400 block.
no
350 and 400 models had the TH-350, the 454 models had the TH-400
Yes. They are identical because externally the 350 and 400 are also identical.
I assume you are wanting to replace A 350 with A 400? It will run but not correctly, It probably won't even have the power of the 350, You need to either put on A carboretor or get an aftermarket injection system, Also if it is newer than 92' the auto tranny will not work because it is controlled by A computer that takes info. from the motor.
350
Every part that is in the 400 is heaver and bigger then the 350. The 350 turbo is light duty, but can be modified to make it tuff. The 400 is already tough from the factory.
No, a Honda Rancher 350 carburetor will not work on a Honda Rancher 400. The difference in the sizes of the 350 and 400 carburetors are not compatible with each other.
