I will be using B16b block with b20b crank & rods, my question is what main bearing and rod bearing should i use? is it the size of the b20b bearings for the main bearings or the b16b size main bearings? I think the rod bearing should i used is for b20b since im using eagle rods for b20b. Also is it the main caps of b16b the same as the B20b? what main caps should i used to the 89mm cranks to be drop off to B16b block?
