What else?
 

I picked up a LS6 intake awhile back and I have a F-body water pump so what else will I need to do the swap? I'm assuming F-body fuel rails and crossover? What about the TB? Going on a 99 5.3 with return style fuel system.

Is the gain worth the trouble or should I just sell the intake/water pump and stick with the truck intake?

fbody alt and bracket, fbody powersteering pump and bracket, and tensioner

Thats not required though? just looks better correct?

are you using the relocation pulley? if not you need all the fbody accessories

I'm still deciding if its worth it. Trying to find out besides what I have what else do I need?

heres my 2000 with an ls1 intake, mallory fpr, ls1 injectors, ls1 fuel injector pigtails, aluminum fuel rails with steel braided lines. i cut up the stock rails and used some tube adaptors with an fittings that go back to the stock lines. it caught on fire a few days before this is the reason for the soot on the fire wall http://i24.photobucket.com/albums/c3...1/100_1014.jpg

A Speartech idler pulley relocation bracket about $85.00, I used a water pump for a 07 NNBS think part # 12600767 about $150.00, it cleared my dirve by cable TB and a top raditaor hose off an 07 NNBS part # 19130027 about $52.00. I used the stock fuel rails off a 04 Z06, and an aftermarket fuel pressure regulator with a return line and car style injectors when we did my LS6 swap.

Here's a picture with the water pump, fuel rails and injectors installed.

i really dont see too much difference between this and the truck intake, other than a bunch of mounting brakets and vac ports on the truck intake... does the ls1 intake flow better or something?
