I'm new to this site, I have been reading alot on the lt1. Have seen a lot of great advice and hopping I can get some to. I have a 97 z28 that is running 11:1 compression, pcm has been tuned has a comp cam 503° and 1.6 roller rockers. So the help I need is this.

1. I have two injectors that have gone bad and have a set of ls1 injectors given to me. Read the comments on this but am confused from all the research. They are slightly shorter than mine so how do I get them to work without leaking.

2. What plug should I run and what gap.

Just want to say I'm glad to be a new member and look foward to the advise.

 

1. You can buy spacers to fill the gap for shorter injectors. Here is an example. http://www.summitracing.com/parts/FST-146025-KIT/

2. I ran NGK TR55 plugs gapped at .050. No real need to go with a different gap with your setup.
