Q: well i need to biult my bottom end. piston 3 ring is out causing oil 2 come up thru my tube seals. if imma do the work. what bootom end would go good with my ls head. im keeping the head since the head is find. so just wonering if i should my my bottom ened for 1400 or maybe build a different bottom end instead.?

A: B20 stock sleeves are way fragile for boost. Keep your LS bottom end, it will hold a good amount of boost with the right tune. If anything, re-sleeve it and give it some forged internals. May save yourself some headache later on.
