OnE Ls1 2 HaTe

So I just picked up this 2000 Lq4 block with 140k on it. I was planning to race this motor , so i wanted to freshin it up a bit. Do you guys recomed just changing the main bearings, piston rings and rod bolts? Or should i do a whole rebuild, where I bore the block out and everything? Any feed back is appricated, thanx!

I thing that depends on what your expecting for HP numbers.. are you going to spray or FI it ?

Just doing a quick refresh or a H/C setup, I think you will be ok as long as your not trying to go over 400-425 (?)... anything over the 425+ numbers, I would suggest new pistons and getting the rotating assembly re-balanced. If your going to spray or FI it.. forged lower end.

My .02 cents

use a bleed down gauge to check ring and valve seal, look at bearings and see what they look like. depends on how hard ur gonna push it but with those kind of miles i would think that at least rod bolts, oil pump and a light hone with new rings, bearings and gaskets would b a good idea.

sense you already have the motor and it sounds like you have a decent budget in mind i would do new piston and rings and bearings ,mill the heads and have the heads rebuilt, do a cam and springs of coarse lifter etc etc.
but if you want to spend another grand or so just do a 408.
good luck
