Spark Plugs?

[grandprixgtp_91]

Ok now im stumped, i dont know what kind of plugs to use in my crate engine. its a 96/97 crate motor, it did not have plugs in it when i got it, i will be using a 91 ignition system on it, can i use the 91 plugs R42LTSM ?
or will this hurt my new crate engine? can i even use a 91 ignition system on this motor? i dont see why the 91 equipment wont work. well any input would be geat i do know that the 96/97 engines did have platinum plugs tho. thanks

I think almost all GM DIS ignition systems haven't really changed to much over their run. So, it shouldn't be much of a problem. As for plugs I would go with either the stock AC's for the 96 model year, or just some rapid fires.

AC's are good plugs...Thats the only plug that will hold up in my banshee...

AC's are what I would use. Using the 96-97 plugs should be fine with the 91 ignition system.

ok sounds good, does anybody know the ac delco spark plug size and gap for 96/97 engines?

thanks

I recommend AC Rapidfire 8's. I run them in both of our LQ-1s and they are excellent!
