The thing about the Edelbrock and Harrop decision to use the 1320 out of the box is there is lots of capacity to increase boost later. Cosworth decided to use the smaller Supercharger which better matches the 2.0 capacity. Cosworth says they could get more than 300 HP out of this size but anything over 290 is unsafe for the stock bottom end, by which they mean the rods which we know will bend at very high bmep.
