sst120 VS 175 merc
hi i need a very fast 2 lt motor and i can get either a sst120 {stock} or a fully modded 175 merc in your opinion what would be better?
cheers thunderstruck

SST120 would be based on a later block, so probably better to get parts for. Otherwise, the std 2L could be made to run as well or better than a stock 120.

Which engine rotation are you looking for?

the engine rotation does not really matter
