Check this out. A 270 slant 6

Well Dart Guy technically speaking a 225 is a stroker 170 isn't it? Thats like the guys over here that swear blind they had one of those 318 "HEMIS" I usually say that must be worth a lot of money being the only one made!
Naw. The 225 is a stroked 198. The 170 has a different block. lol
