Re: My 68 C10 Blowen LS2
68 C10 LS2,
Any insight on the install process for the LS2 V-8? Did you have to make custom motor mounts, use a custom oilpan, custom headers, or what? I have a '71 C10 that I already installed a TH700-R4 with lock-up converter (did the slide the trans mount back install like you), now I'm thinking about upgrading to an LS engine from a car or truck. Obviously I'll need an electric fuel pump and electric cooling fans as the LS-series engines have no mechanical fan ... but what else am I in for. With a 1967 Camaro RS convertible I built years ago, I upgraded to an LT1 engine with a factory computer ... but had to turn off the VATS (Vehicle Anti Theft Sensor) to make the system jive with the old Camaro. Any funny stuff that you had to do with the computer? |

Re: My 68 C10 Blowen LS2
If I wanted to install a new LS engine (such as 2008 or newer) and wanted to eliminate the factory throttle-by-wire setup, what mechanical throttle-body would I use (stock from another year engine, aftermarket or what)?

Re: My 68 C10 Blowen LS2
I dont know if you can. All the sensors in the motor are different from 99-02, 03-06/early07, and late07-present.

Re: My 68 C10 Blowen LS2
Kiwi, why would you want to eliminate the electronic throttle? It makes setting up cruise control real easy, can be tuned how you like it. And the newer throttle bodies are pretty good size.

Re: My 68 C10 Blowen LS2
68 C10 LS2 (or anyone who knows),
It has been a busy weekend as I am in the midst of getting a brand new LS3 (426 hp) pulled from a 2010 Camaro SS. I learned that GM sells a "run kit" that includes most everything needed to wire a new LS engine to an older vehicle including a proper computer, wiring harness, and a special gizmo that attaches to an old-school throttle that converts it for use with a drive-by-wire throttle system. I plan on installing the engine in my 1971 C10 but have a few questions: 1. What motor mounts did you use ... and are you happy with them? 2. Did you retain the factory A/C pump from the new engine ... and if so, were there any clearance issues with the stock frame? 3. Did your TH400 bolt up to the back of the new EFI engine without problems? (I already retrofit a TH700-R4 to my truck and I'm hoping that the trans will bolt up to the new LS3 engine without problem.) John |

Re: My 68 C10 Blowen LS2
Well i finally got the motor running, took it out driving and the tune is WAY OFF!!!! I cant give it more than 1/3 throttle and the gas mileage SUCKS!!! I mean its so bad i drove it 10miles and burned 6 gal of E85 (but it will it 10 psi of boost at 3000rpm). So now where to take it for the tune!?!?!?!

Re: My 68 C10 Blowen LS2
First time in this thread. Wow, truck looks great, too bad you're having so many issues. Where in MN are you at? I'm by fairfax. I think you're almost best off working your own tune out with EFI Live or HP Tuners. That way it's how you want it, and you can tune it on the street, track, dyno, etc and not have to take it to a guy every time.

Re: My 68 C10 Blowen LS2
I dont know about alcohol or how gas mileage works with that but to run E85 i do know its 30% more fuel than reg gas. Before i was getting about 15-16mpg with the old setup so i would guess that i shouldnt be less than 10mpg.

Re: My 68 C10 Blowen LS2
Well here you go guys and gals. Pics of the new motor setup. I still have to make a new intake tube so it stops sucking hot air from the radaitor. Sorry no video's of the motor running since the tune is so far off.

Re: My 68 C10 Blowen LS2
Looks sweet! Are you running a boost referenced fuel pressure regulator?

Re: My 68 C10 Blowen LS2
Well i havent logged in in almost a month, been very busy. So heres the update on the truck. I bought HP tunners and now able to send the tunes via e-mail to my tuner in Vegas. I got a new tune finally yesterday, it runs a 1000x's better but still no where near its full power. I can now give it full throttle and the highest boost level ive seen so far is 16 psi!!! I dont know of any root style blower that hits that high of boost (a least i havent heard of any).
