When I mean breathe properly I mean a 3L that makes big power something north of 260whp or so. There are a ton of m20 200-220whp but north of 230 the number of engines drops off big time. When you look at the big strokers 3L+ there are few if any making big power, most are smaller engines because with a slightly smaller engine it works better with a stock or very mild head work. The reason is the long stroke really brings forward the bad features of the stock head
