i am in the midst of building an 18 hp oppy. splash lube. not a puller or racer just a kick my brother (you know what) around the yard. i have an 18 hp in my suburban and it needs a little more. i have a set of heads and cam from a 20 hp oppy and wanted to know if the stock rods with the oiling mods would last. not going over 4k rpm. the intake ports will get massaged out a little but other than that its gonna more or less be stock. so will it last or will i have to shell out all kinds of money on those arc rods ?

I did the oil mods. Fairly straight forward. Thaks for the help

im new to this fourm, but not new to engines by any means. how ever all my experience is on industrial diesels. so with that in mind... i have a 18 hp twin opposed briggs im putting in one of my suburbans. i have read a lot about the oil mods to keep these things alive but cannot seem to find them when i do a search. as i have the engine tore apart and am in the middle of rebuilding it i would like to make it last for as long as i can. ie my cummins makes 650hp and has 243k miles on it. i just want good power and it to last as long as it can. any help is greatly appreciated.
