my question is what main bearings do i use? the z6 or y8 i need to know from some one that has this set up. i read some where on "google" where you need to mix match bearings from both engines. is this true? i really want to know from some one with experience not from some one that has no idea and types in random stuff to look cool. i do understand the z6 crank is a perfect fit. is there any this else that i need to changeor any thing else i use from the y8. like oil pump and crank pulley:fblobla ugh:?
