Good day all,
I am n ew to the Camaro community, normally play with corvette. but I came upon a 94 Z28 with 77K miles, it sat for several years. It needs some attention, got it running, before I can drive with some confidence I need the cooling system upgraded. New water pump and the works. What's the trick with the water pump replacement? Is it the usual stuff, get things out of the way and remove any mount bolts and re-install a new pump. I understand the Opti spark might get wet. Any tricks in keeping that dry during the pump replacement. Thanks in advance.
Ben

Did one of your previous Corvettes have the LT1 engine? If not, there are some unique features of a “hidden” bolt, the gear driven water pump, timing cover driveshaft seal install, bleeding air from the cooling system, etc.. The Opti can be protected by stuffing rags on top of it.

One of the best sources of LT1 info on the Internet is the Shoebox site:

I got hooked on the classic cars, 1941 Special Deluxe Chevy and soon a 1937 ford Coupe with flathead V8. The Camaro was a bonus from my motorcycle purchase. I thought I would play with it with some bolt on for some added power. I drove it after I replace the starter; this car has some tq. I am going to apply some more modern upgrades to it. Carbon fiber inside, hood and trunk wrap. I have some C4 ZR1 wheels; I was wondering if they will fit on this car?

Depends on whether they are ZR1 wheels (may stick outside the fenders) or ZR1/Grand Sport offset wheels (tuck in nicely under the fenders). The 17”x11.0” rears may require some minor inner fender modifications.
