140000 on stock Ls1...rebuild? I am in the midst of purchasing my 4th Ls1 car at the age of 17. It is a 2000 Trans Am Ws6 with 140,000 on the clock (6-speed). After i get the car painted I am going to look into rebuilding the engine. I will have all the work done by a local shop hopefully (weber racing). What all should i be replacing and what parts would you reccomend? What kind of price am i looking at? I would really like to do a mild cam with better valvetrain setup maybe roller rockers? Help a newbie out

Better get a built shortblock with forged stuff from a reputed LSX builder. Plan on ~$3K
Heads can be refreshed at your shop. Cam, well by the time you rebuilt, we'll talk about it.
In the meanwhile do some searching a thread reading. Plenty combos here.

no, i was just wondering since it looks like thats the original motor if i should rebuild the top end before it blows up? The motor runs very strong, and smokes none and makes no noise. Should i be concerned?

Bearings wear out, you spend over $3K in mods only to to do it again when bearings let go.
The shortblock is the heart of your combo, while the block is in good order, rebuild and throw a cam/heads on there.

Keep the engine for now and keep running it as is. Read up, do research, and figure out what your plan is. In the meantime you can save up some money to make your budget a little more forgiving. Then, when you're sure of what you want and where you're gonna go with the car, execute the plan.
140k miles isn't bad. If the engine shows no signs of issues, then it's probably fine. I agree with Predator-Z and wouldn't do any work without getting a new shortblock, but to keep it stock now and just drive the car a bit is perfectly fine.

How about buying a new shortblock outright? Then as money allows, get the cam, heads, oil pump, lifters and pushrods for it. Then when youre motor starts to smoke or lose oil pressure, you can pretty much just swap over the pan and accessories. Who knows, you might be ready to go well before your current motor goes south. Might be worth a couple hundred bucks as a core.
