Green LJRub The Trailblazer engine is 295hp. There is an optional Alum 5.3HO(L33) in the 05-07 trucks, and it was 325hp.
I'm just getting the trailblazer engine. I think 100hp extra will be enough! plus its losing 90lbs and moving the weight back 8 or 10 inches.

sounds good man, I had a hard time deciding also. And if had known then what I know now I would have got the 2006 5.3 Alu block one I had found. I didnt know that the 2008 had a harder to work with ECU than the pre 08 ver. There are way fewer 08 and up for that reason I found out.

What engine mounts did you use?
Advanced Adapters weld in,

I got her back on the road last night with the install of the Tom Woods Shaft

First tests are better brakes by far and no vibrations. I did a little off road to test the Limited slip and its working fine.

jeeptester also did a SYE and removed the skid plate spacers. The v8 needed the improved angle as well
05-18-2013 08:30 AM
jeeptester got the brake lines run and just waiting on Tom Woods now :-)

jeeptester Update on axle swap. I have the axle test fitted and welding and finishing.
Here is a test fit pic and how the shock brackets worked out .

Carrier was out, and the slight play I was talking about is front to rear, slight drag turning , but no loosness

I had 31" tires and it seemed to have more power with that ratio but I thought it ran a little higher , so I'm thinking this ratio 35"-4l60e-4.10 might be best for daily driver and wheeling !and decent MPG

11-17-2012 08:01 PM
jeeptester It does have a crush sleeve , it feels ok to me turns with light pressure slight play front to back. I was going to do the in lb test but my torque wrench started at 240 in lbs and the one at the store started at 120 . And the book said 16 in lbs, so I used the ........method

My MPG is around 16, it was doing better with the 31" tires I think around 18 MPG, but I think for 5" lift and heavy 35" tires and the aerodynamics of a shoe box 16 is not too bad.

Next is brakes and lines. Then roll under Jeep and check alignment before finish welding.

I guess I'll give tom woods a call after that.
11-17-2012 05:37 PM
chevymad If you have a crush sleeve on the pinion you have to tighten until you take the clearance out. Then SLOWLY tighten til you get the right preload. If you aren't using a crush sleeve then it has to be shimmed until the correct preload is set. Crush sleeves can take ALOT of torque before they crush. I usually use a 3ft pipe wrench to hold the pinion while using a 3/4" breaker bar and cheater on the nut.

lindel I had the 4.8L in my 03 Silverado LS. You'll have more than enough power. My mileage averaged around 21 mpg on the highway.

I got the gears in. Only thing was I forgot spring clip lol so take it back apart and put it in

SO today I was putting in the pinon shaft and nut with all new bearings. I have read a lot of how tos about this and they all say tighten to 140 lbs and then check for preload. well what Im getting is the pinion shaft is loooooooose with even 160 lbs . no were close

So what am I doing wrong, basically the bearings are not getting tight , my instincts say to add shims behind the nut in front of the front bearing. But Im unsure if thats right.

Or do I ignore the torque setting and just keep tighten until it either gets tight or breaks? lol

Any Ideas
Well I think I figured it out, it looks to me to be tighten until tight NOT torque.

On the water it still does it I have just learned to ck it from time to time and add. And it is a new cap

Green LJRub I would say its probably the cap. Is it new?
09-07-2012 01:05 AM
scribble77 Bad cap?
09-06-2012 04:02 PM
jeeptester I'm having a little trouble getting the rad to pull water from the bottle if it needs it. It will just get low and not pull ,
Any ideas what could cause this?

I have no idea on the axel. I have never setup one up. If im going to go through that much trouble, im doing it to some Dana 60's! haha
Yea I thought about those but it came down to $$ lol I can do the 8.8 myself for about $900 and most all new parts, and that leaves more $ for other upgrades

truss question

Im trying to put the control arm brackets on the 8.8 ,

Was thinking the instructions say tack weld and put under jeep. Im thinking fasten the brackets to the arms roll axle under Jeep and tack weld brackets while arm is holding them in place. That way they have to in correct location and will not be in any load.
Agree?

LS6 intake, Port-n-polish the heads, and maybe a cam.
I plan on keeping my 6spd too! It will simplify the install a little.
I looked at doing the alu block one as well, but for me Im thinking if it ever overheated then it would be very bad. Not sure if thats the case or not but it cant be as tough as the iron block IMO. And working out the bugs Ive got mine hot two or three times. What six speed you got?
