Ls1 2000 Vs 2002

[DAT240Z]

I have found two ls1's for my swap a 2000 and a 02. I wanted to know are there any big differents in the two engines.

I'd go for the 2002, it'll have the LS6 intake and possibly LS6 block. Also no EGR on a 2002. Good luck with the swap!

Was the PCV oil issue fixed beginning on the LS2 or also late on the LS1? The interior 'windowing' to keep crankcase pressure equal?

I think 2000 was the year they redesigned the block for better window's/oiling. It is the 98-99's that had the old design.

 

The LS6 motor had a valley cover with a redesigned vent system that is suppose to reduce the oiling issue. ls1.com has a write up on how to switch to the newer valley cover.

 

Like someone said the 2002's have the better LS6 intake. Some people claim that in late 2002 GM ran out of the old blocks and shipped F body's with LS6 blocks.

early 2000 motors had 853 heads, late 2000 had 241 heads. The 2000 was the first year for the revised block that allowed for better oil return so you dont spin bearings. has LS1 intake and a bigger cam than 2001 up motors.

 

2002 motor has better redesigned rod bolts 241 heads and the LS6 intake. has a smaller cam (not much smaller) also has the good oil return. it dosent matter if its an LS6 block. the LS6 block is actualy weaker and the LS1 block is more desirable. if there is a price diffrence. i would buy the cheaper one. you are going to want to replace the rod bolts reguardless. and a brand spanking new LS6 intake to your door is like $400, but if you are going to cam it or put heads on it you will want a single plane carbed intake with injectors and a huge TB anyways.
