Just a heads up. I had a terrible time with my FAST rails. They leaked like crazy and would not seal around the injector. The mounts had way too much flex in them. I picked up a set of Aeromotives and it fixed the problem. Not saying you will have the same problem, just something to watch out for when you get some fuel flowing...

Thanks for the heads up. I'll trial fit my injectors to see if anything obvious is wrong.

I was talking with my machinist and, after he pulled the motor down, he gave me a status on the 90K motor. Crank good, bearings really good, oil ring land kinda glued. After a bit of discussion, we decided to go with the Callies Compstar forged H-Beam rods and Wiseco pistons and a good ring pack.
Lol.. My "Junkyard" motor has turned out to be something totally different. It's going to basically be a completely rebuilt motor. Ah well, Should be good for a very long time anyway.

The original plan was to rebuild it and put the 5.3 in there temporarily while the lt1 was being refreshed. The original intention was that this 5.3 was just going to be a junkyard motor. Now that the 5.3 will be a fresh motor, I'm not sure.

Update(11/29/2014)- Having some time off around Thanksgiving and bored to tears, I started just looking around the net for any posts/forums that pertained to 5.3's using the LS9 cam. Now, for certain, there's documented Dyno comparisons by major automotive magazines that show measured differences between each GM factory offered LSx cam and the LS9 cam out on top. It was astonishing (to me) that one could switch nothing but factory street cams and tune but gain the better part of 100 hp in the process.
But, that was for Naturally aspirated motors. The posts/threads that I found(a ton of them by the way) indicated the LS9 cam for a street/strip turbo application would yield a soggy bottom end. One encouraging discover though was that lots and lots of people with turbo 5.3's were effusive in their praise for a cam I'd never heard of before. The "Triple 12". Many of you reading that will say "well, duh..". Lol.. So, after reading the same/similar impressions on several different forums and seeing the cam attributed to a user known as STOCK48, I sought a website/store but couldn't find him other than forum references. I posted here in ls1tech.com and several good people told me to just send him a PM and that he would respond. Sure enough, Jarret/STOCK48 contacted me. I gave him my cars spec's and my goals and the Triple 12 seemed like a good fit. I sent him the paypal payment and, after confirming my compression ratio (I *think* it's going to still be 9.5) with my machinist today and conveying that to Jarret, the cam will be sent in 3 to 5 business days. Jarret is in California. Seems like a great guy to deal with.

20 feet of PTFE -8 fuel line,
20 feet of PTFE -6 fuel line,
2 -8AN elbows...
Since I plan on occasionally running E85 in the Spring, I thought I'd better run better lines. My in-tank setup (twin pumps, one 255 walbro, the other a Aeromotive 340 lph) is almost done. Just have to get a couple more fittings. I wish there were a shop with all the fittings available so I could just go over there and piece my system together at once. It's somewhat frustrating to buy what I *think* I need, only to assemble it to a point and realize I need something else.
PTFE lines in -6 and -8 size. Twenty feet each.<br/>

Ordered some 'light reading' and received it to day. "Master EFI Tuner for GM EFI" by Dan Maslic.
By Dan Maslic
In the book, he not only explains a lot of base terminology for the lay person but also examples of Real World tuning using HPTuning AND EFILive...
I've been playing with the free demo version of HPTuners while my purchased HPTuner Pro is enroute to the house. I like the layout of the book and it seems pretty detailed. I'm changing the values in the demo file just like the book says and so far, everything matches up.

More fuel system stuff (and my Isky Triple 12 cam!) arrived today...
I decided, at least initially, I'm going use the 2000 Corvette combo filter/58psi fuel regulator. Hooking it up to -8an and -6an PTFE lines.
Unassembled. The 'Y' is going to be on my twin fuel pump setup.
Partially assembled. The -6 an outlet will be going onto an -6 to -8 adaptor which we lead to the engine. The inlet is -8an, the return, -6an.
Assembled.

Do yourself a favor and save some headache. Go ahead and buy a boost referenced fuel pressure regulator. You will grossly overpower the vette filter and have very high fuel rail pressure.
