99- first half of 00 are different than the late 00-04 crank pullies. Be CAREFUL to get the. The first were externally balenced motors, and had a matcing crank and flywheel. The later years are internally balenced - and have the crank and flywheel to match those instead.

Created quite a headache for me when my 3.8L fly got on my 4.2L motor by accident during one of many swaps. Couldn't get the vibration out for the life of me, and swapped 3 times before we figured out the issue!!! Even though it might fit right, it won't spin correctly.

 

woah hold on i almost amade a doosie
4.2 take diffrent udp
explanation por favor

 

4.2L cars cranks are internally balenced... so they need the 4.2L crank pulley and matching flywheel.... same as the late 00-04 3.8L got. The 99-early 00 cars where externally balenced. I have an IB flywheel on an EB motor set up.

 

Ok I guess there up for sale or trade, what would be a good price? 90?

 

craigslist for sure! someone will buy it.
