I read every 4.2 swap post on here so I dont want the use the search answere.

I have a 2000 3.8. There is no weight on the balancer.

But anyways, to stroke your engine to a 4.2, you will definately need a 4.2L crank and connecting rods and pistons at a minimum. If you're manufacture date on your door jam is oct 2000 till about march 2001, you need a new oil pan and flywheel and harmonic balancer as well. If your date is april something 2001.

I've heard it was late 00's+ that went internal.

Late 00 3.8s are actually early 01 spec engines that are internally balanced. If you have one of these.....just use the notes for an 01-up.

Also did the late 00's have the same girdle/tray, oil pan and oil pickup tube as the 01+?

yea in mid 00 the balancer went to internal vs external, its easy to spot you will have a fully round harmonic balancer vs one with a notch in it. I know my 01 was fully round.

I am not sure on the girdle tray (I assume the same) but the rest as far as I know is the same
