I am new to this board, over from T6P! I am a Buick GN guy, but have always loved the good ole chevy 350.

I just bought a 95 Z28 with a blowed headgasket. While repairing that can you guys give me any tips. Performance, maintinace, or just plain help tips!

I read the Tech/FAQ section. Other than the air filter upgrade what is the quickest and easiest mods to these cars. I want to shoot it with at least a 150 shot!
Main reason I bought this car was to play with a little NOS :roflmao:

Well if you're going to have to pull a head off you might as well pull both and get them ported. Not a bad time to throw a cam in either.

Maintenance: Don't get the opti wet!

This was in the FAQ section here
Why do optis fail? Due to its location, the optispark is subject to moisture from several sources. First, driving through high water can submerge the opti completely. Automatic car washes with undercarriage wash can also soak the opti. Secondly, if the water pump suffers bearing failure and coolant comes out the weep hole, the opti can be soaked with coolant. Lastly, NEVER WASH AN LT SERIES MOTOR WITH A HOSE OR HIGH PRESSURE SPRAYER. To wash your motor, use a damp soapy rag and take your time.
Sounds like it works alot like our GN cam positioning sensor! Although the problem about getting wet does not occur.

How about my NOS ?? Any of you guys shooting these things??

The non-vented OPTIs were really notorious for failures due to moisture so they redesigned them to include a vacuum line from the opti to the intake to suck out any moisture that accumulates. My 94Z was converted to vented opti, but I still won't powerwash it.

Ntrous is the easiest way to add HP, but it's not without risks. If you don't have enough fuel system capacity to keep up, you'll risk burning your pistons. A single nozzle wet kit is probably the simplest way to add 150HP. If you run racing fuel, you won't even have to fool with timing to prevent detonation. Just make sure that you have colder plugs and good wires.

If you're gonna be messing with nitrous, especially 150+, make sure you replace your piston rings with nitrous ready piston rings. Then you can hit the juice all day long.
