A couple 6.0 questions

[M16A2]

I did some searching before but cant find much but i know it is out there, anyway, got an 84 short bed reg cab that I will be throwing a 6.0 and t56 in for a summer toy, I am wanting it to be cable operated not DBW any idea what year they switched to DBW? also if I remember correctly the first year or two on the 6.0 they were cast when did the all aluminum ones come out?

[mr spree]

i beleive the aluminum ones will have the DBW. my 2004 6.0 had DBW which is now switched to cable driven

[M16A2]

what brand of conversion did ya go with I have seen a few different ones I assume all it is is a different throttle body? I am goin to have CPW make a custom harness so wiring wont be to much of an issue.

[mr spree]

Im using the truck intake and i took the DBW throttle body off and bought a Cable driven throttle body from a camaro which had the LS1 in it. i beleive its 85mm throttle body. If your going with CPW give jared a call and he will be able to answer any of your questions.

[M16A2]

this would work wouldnt it, it is an LS1 like your but it is a 75mm instead of an 85mm or would that be to small ya think?

[mr spree]

what year is the engine your looking at? this is what Phil has down in the LSx Conversion Information http://www.s10forum.com/forum/f213/l...mation-390967/

For simplicities sake, use the throttle body that is stock on the engine you select.

The F-Body LS1 Engine uses a cable driven 75mm throttle body.

The early LQ4 engines used an 80mm Throttle body. For a stock GM cable throttlebody, this is the best.

Later trucks used an 85mm DBW throttle body.

The Y-Body LS1 used an 85mm DBW throttle body.

The LS2 GTO and Vette used a low profile DBW 90mm Throttle body.

i will be using an 04-05 6.0L from a 2500 or Suburban which I believe they are LQ9 if i remember correctly

[mr spree]

6.0L Escalades are LQ9s. They are rated around 345hp. Its the same engine thats in Silverado SS, and Silverado Max trucks. The 2500 6.0l which is what i have is the LQ4. Surburban is probably the LQ4 also.

[M16A2]

thats right sorry about that I knew it what LQ something. The LQ9 were cast iron blocks i believe while the LQ4 were all aluminum correct.what are the HP and torque ratings for the LQ4's?

[mr spree]

My 2004 LQ4 is cast iron block with aluminum 317 heads. The 5.7l ls1 and 6.0l LS2 have aluminum blocks. The LQ4 i have is rated about 300hp and 360ftlbs.

The 2001 came with the cable tb.

[S15vortecpwr]

2003 started teh dbw throttles. but you can put any tb on the intake.

Just had a friend build a l92 eng for his rock crawler and used a cable driven TB.

[mr spree]

Yup, took my DBW off and added a Cable one

[M16A2]

well the LQ9 I was getting ready to buy just got sold, I did happen to find a L33 5.3 for a descent deal so I will hopefully be picking that up. Is it common to run electric water pumps on these swaps or is the belt driven one better?

[Kampz69]

electric pumps stick out pretty far from the block, it would probably hit your efans...not much room in the front of the engine. i can think of anyone specific that has run an electric pump, so i would say 99% run the stock belt driven pumps.

1999-2002 have cable driven 75mm throttle bodies, these are actually easy to upgrade to say a 90mm cable driven throttle body with an intake or maybe a 102mm FAST truck intake????. Check out the pic I found below on facebook.

2003-2007(classic body style) came with a 75mm DBW Throttle body. These are hard to upgrade to anything because they have a 3 bolt pattern throttle body, the 90mm throttle bodies all have a 4 bolt patern.

2007(new body style) and newer come with a 90mm DBW throttle body.

[Petro]

Hmm...Fast truck intake pretty cool

Well the L33 I am looking at is out of an 2005, so it would be difficult to get a cable TB? Nobody make a conversion from DBW to Cable for late models?

[SweetS10V8]

Nope, You would just have to get a different harness and computer.

Now if your getting your harness from Jared at Current Performance, just have him make it for a cable drive and buy a 1999-2002 cable driven computer.

[M16A2]

yeah i am having jared make me a harness, I would just need to get a TB from an earlier years or what as stated above the switched to a 3 bolt TB instead of 4

[SweetS10V8]

Im no harness expert, Jared will be able to tell you what is and isnt possible.

Your newer engine will have a 58x crank sensor, cable driven engines have a 24x. I think Lingenfelter makes an adaptor.

Your cam sensor is in the front instead of the back most likely too. All things that have to be straightened out with Jared. Youll need an older computer, TAC module, and pedal too.

Personally, Id just run a DBW throttle body..... I do......

[M16A2]

I have heard that the DBW have a little hesitation when you punch it, is this true?

I have dbw and I don't really notice it if it does. I will floor it a couple times tomorrow and test it. Here is a video of me punching it at a 30 roll.

The truck engines didn't go to 58x until 2007 the car engines went to 58x mid year 2006 after all the 24x wheels were used. Like Sweet said there is nothing wrong/ bad about DBW no pros or cons. If you have a truck that was DBW and you want cable then tell Jared and he'll fix you up. But you'll need to make a bracket for the cables since the DBW I intake won't have provisions for it. Most of your answers can be found by reading Phil's sticky.

dont sound like it hesitates to much just alittle because of the kick down of the tranny sounds really good what do you have for an exhaust?

[mr spree]

So i have a cable driven TB on my truck intake and already have the harness from jared.... would i have any problems with using that new Fast truck intake when it comes out SweetS10V8

You can use a Fast intake no problem. Just buy a nice 4 bolt 90mm or larger Cable TB to go with it. If you use the car style buy one of those pulley relocation brackets for truck acc. from speartech.

[SweetS10V8]

Ive found a total of two pictures ANYWHERE on the FAST truck intake, but it means the truck accessory guys can run it without moving anything, it should bolt on! I can not find any other information on it other than "Look what we are working on".

Between the pic I posted earlier and the other one I found in another thread on LS1tech, it looks as if the FAST intake uses a 4 bolt pattern throttle body, like every throttle body has now. Which means most any OEM 90mm DBW or aftermarket 90mm cable throttle body should hook up to it(assuming they made it to work with a 90mm TB, and not just the 102mm).

I don't know if its for cathedral ports(LS1/LS2/LS6) or if its for L92/LS3 ports.

[mr spree]

yea that looks pretty sweet though. Changing my truck intake to the car intake i would need the fuel rails and injectors from the car and wouldnt the harness need to be changed for the injectors
