l98?
Out of curiosity at what point do you think the engine in your car ceases to be a l98. I've changed quite a bit of mine and always kind of wondered where to draw the line as far as calling it a l98. I do still use a ltr type intake but it's not the stocker, heads and camshaft are also not stock, neither are the rockers.

Short answer: The thing that made the L98 a L98 was the TPI. So I guess you could say it is no longer a L98 when the TPI goes away. I have no idea what you would call it other than a SBC.

After the L98, came the LTx line -- with reverse cooling. I'm not sure there was ever a SBC with multi-port FI before the L98. The L98 also has a unique distributor system AFAIK.
Heads changed a couple of times as did the camshaft type. (solid vs roller cam). They were also two bolt vs 4-bolt.
That said, I still call mine an L98 (with a 4-bolt and zero stock parts). Even if I'd gone with the HSR or FIRST intake, it's still the block-style underneath.
Though it's a matter of personal discretion, I'm going to say it's the era of block used -- and that it had MPFI with an ODB1 ECM using traditional cooling.

IMO once the plenum is gone its no longer an L98. The ditributor in our L98 is not unique its just a in cap coil used in many GM vehicles. Even if you are running aftermarket intake and runners it's still an L98. Another thing to take into consideration is the 305s also had the TPI and the heads at least the 113s were offered in crate engines. if you look up block and crank casting #s thy say 350 SBC. So what is really unique to the L98 IDK maybe the exhaust manifolds... My .02

A little more than that IMO...

How many other applications had the same block and crank without the tuned port?
Not that it matters to me really once not stock it is no longer a L98 as that describes all the parts inside and most of the big ones outside. While and F body L98 uses different accessories and brackets it is still an L98 in it's basic form.
I would think if it does not look like an L98 and does not have all the things it came with it is no longer an L98. If a valve spring or valve or rocker arm or intake gasket etc does not fit is it still what it was born. No it is an L98 varient or modified / customized that was originally an L98. It will always be a Gen 1 SBC though. It is all symantics for a purest somewhere that no doubt has clean finger nails and an aversion to wrenches oil etc. but good with a scoring sheet.

Late 80's pickups were 4-bolts. That's what I understand my block came from.
Interestingly enough it is stamped "638" which was also the number on my OEM 2-bolt block. So, the blocks look the same other than the 4-bolt config.
OTOH, Guess I should call it an LSgp. It's much closer to LS power and made by me!
