only difference between this block and a 20R block is the size and shape of the piston, THATS ALL
stock 20 on stock 22 block is 30 or more HP, put bigger valves, ie 22R valves in the 20R head and a nice stage 3-5 LCengineering cam and some dual valvesprings a 38weber, or maybe sidedraft carbs and you can get 200HP
