I don't believe you gonna get 500 even at the engine with just a 4 lbr. Go to NLOC and search for pulley and hp combo's. As far as oil goes only the high price seperators really work. I've installed the other cheapies and nothing worked with high boost.

 

link?

 

true but a 4#er will keep the stock mtor togetther hopefully until he's ready to step up to the plate and go witha built motor


L&S automotive maintainence free oil seperator (what I run on my green truck): http://www.lnsauto.com/articles/ford...01_index.shtml

DMR oil seperator: http://www.dm-racing.net/oil_separator.htm this is a great looking piece

 

I noticed that there is a difference in the exhaust manifolds from the lightning and the NA 5.4... Which is better?

 

the lightning ones have less scavenging

 

So keep the lightning manifolds What do you mean by scavenging?

 

drawing the exhaust out, if it were me I'd run the lightning ones until it came time for long tubes

 

What ngk tr6 spark plug gap should I run with 8-10 lbs of boost, exhaust and CAI?

 

I have never read anywhere that the 2004 Lightnings had an increase of 5 hp with a total of 385 hp until now. Post up the link..........
