'68 C-10 LQ4 - 4L60e Budget Swap - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

chevydog66 · 05-31-2010, 03:56 PM

Why cant you use the original steering column and and shaft and steering box, and just hook up the p/s lines to steering box? Will the stock exhaust manifolds clear steering shaft? I am using ECE motor mounts.

chevydog66 · 05-31-2010, 03:59 PM

Why doesnt' the stock crossmember work with a 4L60? I have the 2004r in it now, but will be removing and selling, I guess.

68GMCCustom · 05-31-2010, 06:25 PM

thats what I'll be using...a 200-4r

Is there a special bracket for the TV cable?

68GMCCustom · 05-31-2010, 07:20 PM

there are special TV cables, then I have also seen special arms/brackets that you mount to the carb (2 different styles) to correct the arm geometry.

200-4r bracket

chevydog66 · 05-31-2010, 07:26 PM

Those are for carb'd motors though, right? Are you going to use the computer/EFI on your 6.0? I plan on using the whole engine management system. I have the TV cable adapter from www.bowtieoverdrives.com to hook up to my Holley in the truck now, but need to figure out if I can adapt the 200 4r to the 6.0 or just get a 4L60 to run with the computer on the 6.0.

68GMCCustom · 05-31-2010, 07:59 PM

I have a brand new LY6 6.0L VVT motor. I am not going EFI for now, and will remove the VVT, EFI intake and use a carb and a 4bbl intake, and the MSD-6LS to fire the coil packs. I'll also swap the cam and springs for a hotter setup, but I am waiting for GM to finally release the LSX dual plane intake for standard decks. Its been in the GMPP catalog since '09. If they don't release the dual plane... I'll get the GM L92/LS3 single plane carb intake and the appropriate cam.

You should be able to tune out the tranny...as if it had a 5 speed stick or something. You may just have to get a ecm/pcm from a truck with a manual trans.

chevydog66 · 05-31-2010, 08:18 PM

Ahhh, ok thanks for the info. I just found this link which answers a lot of my questions. http://67-72chevytrucks.com/vboard/s...&highlight=lq4 Good luck with your build.

eagleuh1 · 05-31-2010, 08:58 PM

Good luck with the build. I'm in the middle of mine as well. What year is the gas tank for and how many gallons. Looks like a fairly nice fit. Nice truck to work on as well.

It's a powdercoated 20 gal. Summit tank with GM sender.

joejbal · 05-31-2010, 09:25 PM

My truck was originally a 3 spd with manual steering.

I had to find an auto column, I want to be able to sit three across (two kids).

I've got that same, albeit used, LY6 from an '07 2500 HD and was pretty sure you couldn't convert it to a manual tune because GM didnt offer a manual behind the LY6. Removing the efi and VVT would change that though, or so I would think

68GMCCustom · 06-01-2010, 07:51 PM

I think VVT "for hot rodding" is still a little ahead of its time. I'm not comfortable with the current engineering designs and fear major breakage in a high performance scenario. I am keeing all my EFI and VVT stuff though...incase one day I decide I would like to have the EFI/VVT and want to swap it back.

You are probably right about it being ahead of its time. I plan to keep mine at near stock power levels for now and keep an eye on what comes up in the world of VVT. I really like what I've seen from Mast Motorsports though, and VVT seems to be a promising direction to go considering the increase in production engine using the technology.

joejbal · 06-02-2010, 03:23 PM

Why not keep the EFI but can the vvt for now?

joejbal · 06-02-2010, 03:25 PM

Here are a few pics.

Everything has the original dirt and grime.

68GMCCustom · 06-02-2010, 03:36 PM

I have EFI in our TBSS...I prefer this setup for my '68 truck:

joejbal · 06-07-2010, 10:34 AM

Here is a pic of the engine, everything installed and running except the air box, and exhaust.

Used the stock rad and a pair of dual fans from a k-car.

The thing sounds and runs great. I got too excited to remember to take a video.

djmachinist · 06-07-2010, 11:22 AM

Subscribing, Nice truck, interesting conversion. Looks like the thing is relatively rust free.

smokinstang70 · 07-30-2010, 11:24 PM

Doing the same swap on my 71.. can you give me more details on the fuel tank... It looks like a great fit!!! you said it came out of a Camaro SS... what year?

Thanks for the info... truck looks great.

mcbassin · 07-30-2010, 11:29 PM

Nice work on the install! who did your harness and pcm reprogram?

corvetteman10 · 07-31-2010, 12:13 AM

subscribed! please keep the info flowing. the more i know the easier mine will be. thanks!

eagleuh1 · 07-31-2010, 07:21 AM

Is it road worthy yet? Real interested in that gas tank. How many gallons? Has it worked out for you? Where did you buy it? Enquiring minds want to know! Mine was on the road, until I decided to do one of those so called complete truck makeovers. Gutted out the cancer yesterday on passenger side. Hope you like the new powerplant. I do.

smokinstang70 · 08-02-2010, 12:40 PM

Any updates? Really interested in the tank info.
