Just to be clear, headers or stock manifolds... BOTH require gaskets where they mate to the cylinder head.- Shaun

A CHRISTMAS MIRACLE!
That's actually Holley's R4 compressor LS adapter bracket pn# 20-133. The stock 5.3 (and probably all LS series engines) ac compressor is on the bottom of the passenger side. You can use it, but you'll have to notch and box the frame for it to fit. Depending on which accessory setup you go with...- Shaun

A CHRISTMAS MIRACLE!
Sorry for taking so long to respond. Yes, i went from the original 700r4 that was in the truck, to the new 4l60e that came with the motor. I used the 1" setback transdapt motor mount adapter plates like I've seen on a lot of other people's threads. This ended up making me have to drill new...- Shaun

fuel sloshing solutions?
Thanks for the reply bud. I was hoping someone would chime in with some sort of fix. I remember seeing a thread about some one retrofitting the 98+ fuel pump hanger/sending unit into an older style pick up, for exactly the problem I'm trying to solve (fuel pump sucking air on hard...- Shaun

5.7-5.3 swap info needed!!
Sorry buddy, i don't really know which direction to tell you to go. But i can tell you, that the power difference alone makes it worth it. For me any way. My 1990 350 was a compared to whatever is in your 97. I remember we had a 98 Cheyenne work truck with the vortec v6 engine, and it would...- Shaun

5.7-5.3 swap info needed!!
It depends on what year truck you're putting it in. The motor mount plates i think are the same for all 5.7 to LS style swaps in our year range. You can use the stock exhaust manifolds if available with the engine, just make sure you also got the 8" pieces that have the o2 bungs. What are you...- Shaun

fuel sloshing solutions?
Hey everybody, it's been a while since I've been on here. I've got a 1990 RCSB, with a 5.3/4L65E swap. The problem I'm having (and this happened even before the swap), is that if I'm a little above a quarter tank or lower, and i accelerate hard, the engine bogs down. Now, i know it's because the...- Shaun

intercooler ideas
I just purchased a vortech v2sc kit for 99-06 4.8s-6.0s. Now i know it's meant for that truck year, but it's going in my 90 5.3 swap. The only issue in having is the intake tube that routes over the fan shroud doesn't fit. So the remedy is going to be routing instead of over the fan shroud...- Shaun

What mounts/pan/ accessories everybody running?? Any T56 guys out there?
i'm running an 03 LM7 in my 1990 regular cab short bed, with a 4/6 drop. I'm using the stock 5.3 exhaust manifolds, Oil Pan, and all stock 5.3 belt driven accessories, EXCEPT the AC.

idling and shifting issues
Hey, thanks for all of your help. A few updates...i've reflashed the PCM which didnt help. Turns out the Program that was originally setup in the pcm was for a 3500 express van with a 6.0/4L80E. BUT, the tuner changed the segments and such for a 5.3/4L60E. And there was one of the tables that he...- Shaun

idling and shifting issues
Upon further research, I've found out that a P0717 is a code for the 4L80E. I have a 4L60E. When I did my swap, the guy that flashed my pcm put the program for a 2003 Chevy express 3500 with a 6.0 engine (since I was switching to DBC, from the DBW throttle body). My scanner shows it's a 03...- Shaun

idling and shifting issues
Ok, so after putting a second iac, the high idle has gone away. The intermittent shifting in and out issues are still present. Went out today and got a pretty decent scanner with live data. It also lets you record data, so you can drive and then view what happened at the moment the "fault"...- Shaun
