Need help!
Need help! im looking into buying a motor out of a 97 vette... can anyone give advice on a motor out of this particular car... i know the guy said it has 806 heads? are there any major concerns i should look for? thanks
If I were you I would just buy an 00 up LS motor..
I have heard that the oil passages on the 97-98 blocks were pretty small, and that was the problem gm fixed on the 99?-04? blocks. Basically the passages were 2 small holes side by side and the later blocks had just a big opening back there. Honestly it wont be an issue until you get into the higher hp ranges.

Honestly I would not worry about it, people on here tend to over exaggerate things sometimes. Its like it you ask about a 98 F body everyone will say "oh I wouldn't buy it b/c there PCMs are different and cant be tuned" when in fact its just a different PCM that is a little bit harder to tune but not a deal breaker by any means. Its how things work as time goes on technology gets better, but that doesn't make older stuff so fragile when you add a cam its going to blow up. At the end of the day a LS1 is a LS1 with some MINOR differences between years.

Yep, people on the internet (especially people that are new to the hobby, or to these cars specifically) sometimes take little bits of info that they read, and over time turn it into something that sounds like a huge problem....way bigger than it actually is. I see it all the time, and these people would have you believe that only the latest possibile version of anything/everything is good, and that everything before that was junk. Frankly, it's just not anywhere near that extreme, nor that black and white.
The internet is filled with rumors and exaggerations. It often can be difficult to navigate through all the bullshit.
The only bad thing that I've been told about or experienced is the 97-98 LS1 motors need the rod bolts replaced if your planning to spinning the motor past 6000 rpms. If your planning on putting a 97-98 motor in a later year model camaro then you will use the later models sensors to be correct.

It is true that the rod bolts are weaker on these, and they should be upgraded if you intend to take rpms beyond stock levels. However, "6000 rpm" is another exaggeration, as these engines were designed to reach 6200rpm stock. Many people have been ok up to about 6300-6400rpm with the stock '98 rod bolts, but it never hurts to upgrade when going beyond the stock limits.

i see threads all the time asking "do i NEED rod bolts?"
simply put, if your not turning past 6200 RPM's, no...but why not? its not like its insanely expensive and it doesnt have any negatives besides the rods needing resized.
its reasonably priced peace of mind...id never build an LS engine ever without adding ARP rod bolts. period.
Me and TONS of people on here spin/spun 98's to 6500 no problem. I touched 6700 a few times and #7 ringland gave up first..... IMO 6500 is safe and I wouldn't think twice about it but I think it is a roulette game after that... many get away with it but a few don't....
why risk it? just to save 100 bucks?
