Are there any year LS1 engines to avoid when doing a conversion?

Thanks

The later ones (2001 and on) have improved oiling and some other internal block changes.

Latest and lowest miles is best.. but depending on what your going to use it for and how you drive it. Even a 97-98 can be a good value and be completely ok for a DD or crusier swap.

People will frame the older Gen III engine, but they can be a cheaper $ Swap if your just updating for a cruiser or driver.

2001 and newer deleted the EGR. One less thing to have to pass emissions testing.

isnt the head flow different, and cam?

98/99 heads (853's?) not as good as 241's which are not as good as 243's

98/99/2000 cams were bigger than those found in the 01's and 02's.

Im not 100% on that but am trying to find out where i read that (was on here)

i would say the only year to stray away from would be 98 f body because they run a different compter. but the later ones do have upgraded rod bolts and ls6 intakes and like said some improved oiling.

if you decide to go with forced induction, then dont go with a 98 if possible. they are`nt as tuner friendly as the 99-02 pcms

I'd go with 01 or newer because they already have the LS6 intake, no EGR to delete, 28.8# injectors, and newer.

Thanks. I just put a deposit on an 03 from a Vette.
