Im a new member. My biggest questions are in regard to the L98 powerplant I'm dropping into my 1986 Z28. I've heard many takes on the subject of the fuel demands of the 5.7 vs the 5.0 liter my car was originally equiped with both being tuned port injection.
1- do I need an adjustable fuel pressure regulator?
2- do I need a computer from a 5.7 tpi car?
3- do I need a power chip for my big cam and head porting?
4- do I need a maf/ knock/ o2 sensor from a 5.7?
5- can I get away w/ out a.i.r. if emissions is no problem?
6- are there idler pulleys available for ac delete w/ serpentine systems? for a.i.r. pumps?
7- where can I find repacement double-flared fuel lines to connect my fuel rail to the rubber lines on the chassis? (no longer manufactured by gm)
If anyone could answer any of these questions, it would be awesome. I can also be reached at scooted45@yahoo.com

 

1 - I don't think so, but not sure
2 - No
3 - Possibly
4 - Yes
5 - It will be fine without thr AIR system
6 - Yes, I think GM still makes the AC delete pulley
7- No idea

 

thanks guy, I was starting to think no one answered these things.
my old fuel lines from the 5.0 were different as they came from a motor with vee blelt acessory system. They don't clear the larger serpentine brackets. GM discontinued these lines which are unique in that they use o-rings and male fittings. scooted45@yahoo.com
