See I have the TB...can't remember for the life of me where I got it but researched the number and that's the one I need. The tbss intakes are around 140 new on eBay. I might check on fuel rails too. I'd rather get it all setup off the truck beings it's my DD than to dick around with making it work within a certain timeframe and dealing with Murphy's law. So the tbss/nnbs rails are the same correct?

Remember all of the Gen IV 4.8's and 5.3's got the same intake as the TBSS and if you can find one off a flex fuel truck it should come with 36# injectors instead of the stock TBSS injectors that are 29#. If you still have the stock '03 5.3 injectors on your truck I think they're around 25# so either should be an upgrade for you. FWIW I found my TBSS intake for $140 (w/TB, injectors, fuel rails, and sensors) and then picked up a new set of the 36# injectors for $55 off ebay.

you mean 78 right? the stock size is 78 and the 4 bolt is 87. but ill prolly run the 87 since this will be a forced induction build. but yes i will still port and polish the one i end up using
