differences between 800 and 800HO engine
Does anyone know what the actual differences are in between the pre-2010 800 and the 2010 and up 800 HO? Curious what parts interchange, is it just porting and fuel differences or is it deeper? If I were going to build a motor, can I start with the older case and crank and just put the newer 98B4 cast jugs on it and it would be a HO if put into an HO sled with the EFI of the same? Curious, thinking about building another engine is all, just wondered.
