GRAND L 3130 HP VS L3430

[bjess8]

Can anyone tell me if there is a difference between the engines in a L3130
And a L3430?
I have a L3130 and was wondering if all the factory does is turn up the fuel to get the extra 3hp out of it to make it a L3430.

Looks like the 3430 has a little larger displacement...about 9 cu.inches.

The Grand L 3130,3430,and 3830 are basically the same 3 cylinder engine, but the 3430 has a larger bore, and the 3830 has a larger bore and longer stroke ( and takes an extra quart of oil because of the deeper oil pan to accomodate the longer stroke).
