I am really considering swaping a LS1 into my 95, have been eyeing prices.
Is there a better year to look for? I am going to try and get a full swap, is there anything else i should look for?

99-02. Has better heads than the 98. 01-02 I believe has the LS6 intake stock.

pretty much goes in order... 97-98 ok, 99-00 better .... so on generally you want a 99-up but the 97-89s are not bad they just improved little things over the years. like the 97-98 can't be bored even though you rarely need to bore an eng.

but unless your billy bob and think your .030 over 350 is now some sort of fire breathing monster that spits out 1000 hp for every turn of the idle screws on the carter carb. just price the blocks by miles and what you get with them.. you can always search and find out what improvments you feel are best to you and get that year as a minimum

I've heard that the computers on 00 and newer ls1's have better processing (quicker responding/easier to tune) computers than 98-99's. Could be wrong...but i definitely read it on this site...has anyone else heard of this???

99-02 F-body use the same computer. the 98 computer is an oddball.

Thanks for correcting me...i knew i heard something about one of the computers. So the 99-02's have the same computers even though they have different part numbers?

Although the PCM on the 99-02 are interchangeable, there were upgrades done to them during the years to increase the processor speed.

I would stick with a 01-02 as they had the LS6 manifold and the later years seem to have less problems with piston slap and crapy oil pumps.

The newer PCM's have more RAM and a slightly faster processor. I'll have to do a little searching again, but I remember finding a page that lists all PCM part numbers and their associated specs. If I recall correctly, the biggest jumps were made mid year '01.

echo above but to add 97-99 used crappy rod bolts that limits safe RPM use. Oil pumps on 99 and older engines were also prone to failure. I run a 99 with Katech rod bolts and a new LS6 oil pump that sees 7K alll the time

I'd look for an 02 if at all possible. A darker color aluminum block also signifies the LS6 alloy that spilled over to some f bodies plus you get the bonus of better rod bolts, oil pump, LS6 intake and possibly better block. The oil passage ways were also inmproved in 01 I believe. Still dont shy away from an older engine just factor in some more mods to bring it up to par with newer versions. If your not going to mod a leave it stock then any of them are fine
