'98 is not a bad year. People who tell you that are mis-informed.
There are some '98 specific differences.

Bad model year?------->not at all
Just some differences is all. Obviously with any car they make certain changes every year to hopefully upgrade performance so of course the later years are a little more refined. You have been given misinformation as far as it being a bad year.

I love my working temp gauge, bigger injectors, and bigger cam(not really). The biggest disadvantages i see about the 98's are the exhaust manifolds, and the ls1 intake(pretty easy fixes). Also if you bust a sensor you will be waiting a little longer because no auto parts place stocks them, and most cant even order them.

And the exhaust manifolds are shared with '99, so that's not a '98 specific thing. As well as the intake being shared with '99 & '00.
'98 injectors are the same size as '01/'02 (although a different part number), and bigger than the '99-'00.
As for the sensor, you must mean the coolant temp sensor right above cyl. #1? I think you can only get that from GM.

The oil pressure sensor is the same deal, i was able to get both through autoclown though.

Heads supposedly flow a little less than the later heads. And the whole computer being different from the later years. My 98 didn't feel all that strong when it was just lid/catback but she rips pretty damn hard now. Once you start modding, you won't notice a difference in power between the years.

Don't get me wrong---I love my 98--BUT, I HATE the inferior 98 pcm. I wish I had a different year for the sole reason of being able to use all the custom SD operating systems and useful tuning tools that 98's cannot utilize. Converting to a 99+ pcm is possible, but an expensive and majorly involved chore for sure.

the only reason i got my '99 is because of the 98's have the coils bolted to the heads whereas the 99+ have them on a bracket (easier plug changes IMO). that was the only real differance why i wanted one more then the other.
