Needs a shorter stock hub or aftermarket hub and damper. The ATI damper I use on my LT1 uses the same hub for all corvette LT1s. It comes with a spacer that slides over the snout before installing the hub on non 1996 engines IOT make it that little bit longer.

That is the main C4 LTx accessary bracket. The alternator, a/c compressor, serp belt tensioner, and power steering pump all mount to this bracket. There is a small metal bracket on the other side to mount the power steering fluid reservoir.

I believe you're looking for a 10128489 - Torsional Damper, LT1
for use on 1992-96 LT1 engines.
and P/N 12550097 hub for use on 1996-97 LT1 engines.
Did you ever go to the LT1 vs LT4 link posted in one of the threads earlier, some of the P/Ns are there?
LINK
IMO finding the engine parts are going to be easy, IDK about getting through Kalifornia's CARB process. Anyone know what it takes to get a older C4 through carb with a 1996 engine? Does it need to be OBDII or should/can he make it a 95 and use OBDI which is easier to tune in the C4 since its not a 1 year only setup?
Or does Kali let the car go by the model year in which case how's it make it through visual?

but have been fairly sedated the last few days here at the old transplant recovery center ... awake enough to roll forward though .. 
remembering everything ... not so good .. bare with me
thanks for specifics ... I need just a little time to reread and assimilate spec info ...
wish I was Borg unit today ... being carbon based has its limitations ..

To Go back Home .. Carbing it up .. Interesting
If you have the plug in the lower front side of the Crank cover... you have a 96 and will need a 96 or 97 crank hub... Good news is the damper seems to be a multi year set up ... (lt1 and LT4 Hub is separate from damper)
The corvette shortblock from 92-96 has the same stats on the rotating assembly that accessories are close so I'm saying chose the accessories you want/need and work from there. The 96 has a Crank Position sensor so the hub is a little bit shorter IOT make up for the space the reluctor takes up on the front of the engine..
RMS is rear main seal LT1 has a 1 piece rear main seal just like the L98 and other late model SBC engines.
If I were in your shoes (Kalifornia) I'd think real hard about fixing the Cross fire or installing a regular SBC based engine before messing with a GEN II (LTX).. or if I was up for fighting CARB I'd shoot for a 6.0 Gen IV or larger...

would you know how to make the Opti spark (which works off the front of the motor) work with a carberated set up ?or
do you know if there is a gear already in place ( at the back of Cam ) to drive a standard HEI distributer ?
did you know that the Lt1 needs that 300 dollar special 4 barral intake ?
I have seen LT1 intakes with and without the ditributer hole
any input is good

If your motor has this type of timing cover, with the crank sensor and mounting bolt holes on the lower left side as viewed from the front of the motor, then it is either a 96 or 97 LTx.
This cover was only available for those two years as a crank position sensor when GM made the change to ODBII.

I would google the state smog referee (not smog station)in your area
There is one at Pierce College in Winnetka Ca 818 area code
Before you even get started, ask..believe me they are your friend. If you do the swap they will inspect it themselves and give you a smog sticker youre good togo from there. There is no "Paying someone" with a swap like this period anyone that says you can is full of it cause 2 yrs later the next shop is gonna look into who approved it in the first place. .
Tell him what you are trying to do he will tell you whats needed and what you can/cant get away with pcm wise, cats etc. You will be super pizzed if you do all this and they tell you changes have got to be made..
You are brave....if it were me Id sell it and put the $ into good heads/intake for your 350..quick freshen up ie bearings etc. Much much eaiser and quicker route, nack on the road sooner . Not trying to discourage but the whole wiring etc part is going to be a PITA unless you can DIY. It will take you quite awhile to do this and make everything work I could be wrong.

LTx = 96/97 LT1 or 96 only LT4. I believe you have determined that this motor is not a LT4 so that only leaves LT1 for 96/97 if your timing cover looks like the one I posted. I think you said it had a crank sensor.
I will need to do some research on the block codes unless someone else can provide 96/97 LT1 block code numbers.

Im with you on that Smog issue ... I attemptt plan " A " see an official Smog Dude and go forward .all above board is " Good stuff "... Thanky for that one !
Im to excited and committed to go back to Mr Cross-Fire .. especially with those 624 lightened steel heads ... hence .. those x-Fire parts and bits are for sale .
It's more likely than not that I now own a LT1 95 or 96, unit ...
I need to Verify the exact year .. thiese stamped engine ID's should tell the story ..
However ... Im not finding them on any code number list's that I have found through my Google search efforts to this point .. someone out there knows ..
Stamped # V05432XA and # IT5H8131 and casting # 10125327
