Changing the Water pump.............
I noticed some dripping antifreeze from the water pump area today on my 95. I will further investigate tomorrow, but assuming that it is the water pump, I will get a new GM unit as well as new GM radiator hoses. The real question is what to do about the opti if anything while I am in there. The car has 58K on it and is running great. I could do nothing, replace the cap and rotor, wires, replace the whole unit, replace it with an MSD.............
Any thoughts?

Your 95 has a better opti set up than the previous LT1s. It's vented and is just better. At 58K you should be able to get another 40 K out of it as long as it wasn't soaked. Replacing the cap and rotor will tell you if the inside is okay. Any signs of rust or moisture, get a new one and possibly go with an after market opti. How about installing a cam? It's a good time to do it.

Well, if the coolant is coming from the weephole on the water pump, your fuct. Its gonna **** all over the Opti. My advice would be to replace the opti at the same time, and yes get some new radiator hoses. The 95-96 opti's have a vent line that sucks all moisture out of the unit, but I would go with a aftermarket opti. If your doing the work yourself, Whatever you do, dont go to a GM dealer for the parts, they will rip you off with there ridiculas prices. I recommend a aftermarket vendor like Mid America Motorworks, or Zip. Good luck.

You guys always make me expend more money. I bought a MSD opti and headers and will start that project mid april
Now, if I was to buy a new cam. Which cam? I assume I should buy new lifters, rods, rollers and I SHOULD get my heads ported. Does anyone sells this as a "Kit"?
Would like to get numbers from you. My 95 LT1 is stock 350, not bored and I'm not looking for a super cam to make the vette turn the coffee over either
