The fuel filter should be on the frame rail right in front of the drivers side rear tire. You can do it without special toold but those fuel line clamps might help.I am not real familiar with LT1's but I know that their opti-spark packs go out often and when they do it suck major ass. There are expensive and hard to install.
If his problems persist after the filter swap I would post this on the Norcal-LS1/LT1 site. There a bunch of LT1 guys that could assist you guys.

I tried replying to this post once but it didn't take. The fuel filter is a good start but also check fuel pressure to isolate a possible dying fuel pump or fuel pressure regulator..... I would hook up a fuel pressure gauge at the shrader valve on the back of the fuel rail and measure for at least 37-41 psi at idle and more with vacuum. If that doesn't work it could also be some dirty plugs. If he's got headers you can change plugs in about 2 hours. If not be prepared for an all day event....

F8L posted a link to your thread on our board:
norcal-ls1.netA very norotious part in the LT1 (Specially the pre95's) is the optispark (basicly a fancy name for a distributor).
IT's a pain in the arse to change, and fi he does he's also better off going to a a vented opti which would require extending the little dong (sorry don't knwo technical name) on the cam.
I know it's a PITA.
But I'm 90% sure it's his optispark (seats under the H20 pump).
Hope this helps... I also hope I am wrong.

Yeah the optisparks are sometimes a PITA. It could be that but I'd check the other stuff first. Surging is usually caused by fuel delivery while stuttering is caused by lack of ignition spark. A swap to a new coil is also a good idea. It's not a bad idea to get an upgraded coil and they aren't that expensive at about 100 bucks for a top of the line Nology (I have one)... And the "dong" that you referred to to swap to a vented opti is more commonly known as the Cam dowel pin. There are two versions, a short for pre 95 non vented optis and the long for 95+ vented optis. I'm still trying to make sure which one I need since I have a 94 block but I have a 95 vented opti. I have all the accessories of a 95 that came off my old motor but the block is 94. It shouldn't matter cause the timing cover is the key so I shouldn't have any trouble mating up the cam to my 95+ opti. I have the long dowel pin cam but the one that came out of the 94 motor was a short pin cam....

Well I changed the Fuel Filter and checked the pump, everything seems good on the fuel delevery side, it feels like it has lost a cylinder im pretty sure its the opti spark I told him to find someone that knows how to change it or take it to a shop thanks for your help guys
