This is like the most fucked up full of misinformation thread I have read on here ever!!!
Just to cover a couple things.
98 computers are a little harder to tune but unless running F/I a decent tuner should have no prob.
A few 01/02 f-bodys had LS6 blocks but in reality there are trade offs for the "bay to bay" bulkhead breathing you hear about for the LS6. Like some builders won't sleeve the LS6 cause they consider them weaker.
01-02 got the better rod bolts not 98 as posted. I have a 98 so I know but mine spin 6500 no probs so far.
i didn't mean to make the 98-99 blocks sound bad. i just meant that gm updated the oil passages. bottom line is any ls1 will be just fine. all depends on what you want to spend really.
There isn't 5HP difference in all LS1 heads. The LS6 243 castings are the desirable OEM heads for these cars.
Yes LS6 intakes came on 01/02 cars.
LSwon...Yes some track cars like at Bondurant that max run on a track had oiling issues but the they fixed the prob by running 15w-50 oil. Their oil temps ran excessively high for long periods. This is not something we should really be concerned with on a streetcar though. I can go into more detail but this post is long enough......
