Any hope for 4WD headers?
How does the MAF work with this? I have an LS7 MAF already but I'm not happy w/my intake setup and thinking of changing over to this. Can I use the LS7 style MAF?
Most find these manifolds are also super easy to weld (cast steel IIRC) so if there is interference you should be able to cut the ends off and reweld to work for your application
Well, we're almost home free now. I have the Tahoe back from the tuner, and after I bought a Nick Williams Throttle Body and replaced the Ballistic Speed unit, it runs fine with a great idle. Dyno...
Well, it looks like I've got a slight air gap in the upper part of the throttle body blade. I was finally able to get the stock connector from the vortec motor to go into the 03 LQ4 IAC I had, but...
Thx for suggestions. So to clarify, the IAC from the vortec motor should be fine, I don't need the one from the LQ9? Tonight on the drive home I did get a P0507 code for high idle.
Also I have...
Ok, I picked up the Tahoe from the tuner, but he is off on vacation and I can't talk to him till he gets back. He still had a problem getting the idle speed down; the throttle blade is completely...

I had to add the spacer to use the dished flexplate; I bought the spacer and new bolts from one of the vendors. Otherwise the stock tranny/torque converter bolted right up. I used the stock a/c...
Well, a big fiasco over the weekend. My oil cooler lines that I had fabbed up (marrying the LSx oil cooler hard line w/stock tahoe hard lines going into the radiator) were joined w/Parker...
Well, after two days I've completed fabbing the exhaust. Probably should have just taken it to the local muffler place, but I'm happy w/the results. All is now quiet on the western front. Now to...
I took out the complete harness so Lextec could integrate LS wires, and I can't remember which side is which WRT the O2 sensors. One of them was mounted to a bracket. Anybody know where this...
Hmmm. I decided to pull the intake elbow off and plug the idle air port off, and it fired right up, and stayed at a high but reasonable 1400 rpm. Didn't feel like a lot of suction on my finger, so...
How can I check this? If that is the case, would it not also cause a problem with the MAF connected?
Thx!
Well, my idle problem is a little more serious than I thought. The truck will not run with the MAF connector in (starts immediately but then dies just as fast); but it will start and race up with...
Well, success at last. I took the LQ4 injectors off the manifold last nite and soaked the ends in Seafoam overnight, just to be safe. This morning I swapped the injectors out, and the old ones did...
Well, I got my new fuel lines installed today and no leaks. But when I try to crank it, my buddy says that only two or three cylinders are firing, all on the driver side. The fuel rail reads 58...
Ok, problem solved. Check the simple stuff first; somehow in my removing the harness and shipping it to lextec--stupidly not putting the fuse box cover back on--I lost the starter relay! When I saw...
Well, I think the top stud does need the wire that I have hooked up there, cuz its a red wire. But if the other stud isn't used, and the remaining wire is a ground (which I thought it was), I still...
Well have most of the engine hooked up, but a couple of remaining issues. I can't remember what wire goes up to the power stud on the side of the fuse box (see pic). I thought the long two wire...
Maybe a major fiasco; the 2010 PS pump doesn't have the electrical connector. I'm sure this has something to do with the variable speed steering; what happens if I leave the newer pump on and don't...
I've been away from home for two weeks, so back at it today. Accessory drive installed. Minor pain in the butt cuz I had a new LS truck accessory drive from my 2010 L96 that I put in my Cutlass;...
I need an additional vacuum source for the PCV; I plan on using the one on top for the vacuum brake. Two options at least; I have some sort of opening that needs a connector that I believe was in...
I have no inspections, but I do like to be clean. I am only reconsidering cuz it may complicate the install. Any inputs on how well the LSx responds either with or without cats?
