ok i have a 85 190e that needs a new motor. I'm leaning towards a straight 6 and it's going mega squirt and turbo. what i would like to know is what the more knowlegeable people on here (Roman) think i would be better off using. single cam or twin cam? 103, 104? what size turbo and so on. i'm looking for around 450-500 hp. hopefully anyways. any help would be great. thank you
