if i do an electric water pump how hard is it to do the non lt1 roller timing chain could i just tig the timing cover closed where the hole is and run a double roller timing chain?

Being that you're a Non-vented opti (92-94 LT1), your timing cover won't accommodate a double roller or LT4 ED timing set. Your only options are the factory piece, or I believe it's Lunati who makes an upgraded timing set for the early cars. If you swap to a Vented opti setup however, a double roller works just fine.

I went with the Summit brand single roller timing chain ($35) when I converted to electric WP. I used a freeze plug and RTV to seal the timing cover. I had a double roller but it wouldn't fit under the timing cover because of the crankshaft position sensor. Depending on what you want the stock chain is fine if you're only doing a WP conversion. Hope this helps!

You have to switch to a vented opti and timing cover from a 95 since the pin that drives the opti is splined into the center of the cam sprocket vs the vented style is driven by a longer dowel in the cam. that being you would also have to replace the dowel pin in the cam with a longer one or get a new cam for the 95+
