any brand plug is fine. depends on what you want to spend on your spark plugs.
.050 95 Z28 only came with 5.7 LT1 motor.
Caca
fireing order 18436572
could be a bad spark plug or bad plug wire.
Use any platinum plug brands really don't matter
I just opened the Chiltons 1993-98 Repair Manual and it says the proper gap for the spark plugs should be .035 for the LT1 (VIN P)!!!! The gap on the 3.4L is .045!!!!! I know I have seen .050 before for the LT1 so I would double check with GM before setting the gap?
It is on the drivers side front, closet to the radiator( the first spark plug).
Bad spark plug or wire? Bad Valve or piston? (do a compression test)
.42-.45 might also try going to autozone or napa. they will tell you.
so far i have found the split fires to work good
just find your distributor behind your water pump and follow the spark plug wires. It is very time consuming and frustrating but you will save ALOT of money doing it your self
The 1993-97s did
