Your best bet would probably be to replace the gauge cluster, but it seems somehow this guy made it work:

Im almost done with my Ls1 transplant in a 94 camaro . I have some sites saved on my other computer Ill post them up when I get on it. If I where you I would sell your PCM and wiring harness and get 98 PCM and harness . it will almost be plug and play .

If i were you I would just buy an ls1 car. i've done it, and if you use a LT1 guage cluster the speedo will work, but the tach will only read half of what the actual RPM's are. if your running headers....get the ls1 rack and pinion, with the knuckle. not sure exactly what you are needing to know, but pm me anytime, i may be able to help.

I did the swap. Had a 2000 V6 Camaro (A4) and swapped a 99 LS1 w/ Tranny (A4) out of a 99 Trans Am into it. It wasn't that difficult a job, really. A new k-member is needed, along with a new radiator....We didn't even bother with the air conditioning crap, so my car's without it, for now. The car needed a new lid, a new Y-pipe as well. The stock V6 gauge cluster worked for me for a good while, but I got tired of pegging it at 120 and not knowing how fast I was going, so I opted for a simple gauge cluster swap outta an 2000 Z28. A mechanical accelerator pedal is also going to be needed, because the V6 is ETC. The only real problem we ran into was the fuel problem. Everyone knows LS1's are returnless style, and have the regulator built into the tank. The V6 of course has a return line, with no regulator in the tank. We ended up keeping the V6 gas tank, and swapping a set of 97-98 Corvette fuel rails with the return line hookups on them, hooked the return line up and never had a problem. I suppose it might've been easier to just ditch the return line and buy an LS1 fuel tank, but we decided to do it a different way. We didn't have to change the rear because my car was ordered with a limited slip, 3.42 rear axle... Hope any of that helped.

well i have long tubes and duals that are going on it so my exhaust isnt going to be an issuse.... what all do i need to convet to the returnless fuel system... i have the fuel tank out of a 2000 T/A.... am i going to have any problems with the sender because i read some where that they changed it in 99.. but if i run a 2000 gauge cluster would that change anything? and also the wiring going up to the cluster... and i going to have to rewire it becuase it is pinned out different or what?
