bodydrop and ls1 swap for a obs.

[1low94]

Ok cool, so will the ls1,2,3,6 intake manifold fit on a lq9 or the L33 5.3 engine? Since I have not made my final decision as to which motor I end up purchasing. Also if anyone can help me out as to go with a cable throttle body or the fly by wire? How difficult would it be if I did go with the fly by wire to do the swap? What are the advantages to using the wire over the cable throttle body?

Dependant on the year of the motor you get it could be as easy as just swapping in a DBW pedal.

My bad the LS3 will only fit the l92 heads cuz they use different ports. U can put l92 heads on a lq4/9.

[DBRODS]

any of the car intakes..ls1, ls6, ls2, ls3, l76 and ls7 will clear.

some say a cable driven TB has better throttle response, ive driven both and i think theyre full of it so either or would be fine, id stick with a DBC prolly be easier in your case.

My question today is if I buy a ls1, lm7 will the 4l60e work out of my 94? It has the 4.3 in it now. It still super smooth shifting and if it would work I would rather use it till I wreck it than buy a second tranny. Any help would be awesome.

IMAG0795.jpgWell I made my purchase lastnight, its an lq9 out of an 05 silvo SS 50k miles with a Texas speed ms4 cam with matching valve trane, shoenfeld headers, 3500 stall in the 4l60, motor came with a Texas speed stand alone harness all ready to go into my 94 chev, the guy I bought it from was putting it into a 91 rcsb so it will work out awesome! Will save me a good deal of cash seeing it came with the harness and swap headers for my truck already, going to drop it off today at Northern Cylinder Head to have them give it a once over to make sure she's all good to go, then from there off to paint. I will prob need to swap out the alt bracket to move it down to fit it under the stock hood on a bodydropped 94 and swap out the truck intake manifold for the ls1 style but no big deal. I'm super pumped to get this rockin!

What a score. I'm not sure if that cam will work very well in a heavy truck. That cam needs atleast a 4000 stall in a light F Body to retain any type of low end torque. I would swap it out for a TSP 228R or maybe a Torquer V3 since you already have a nice stable valvetrain. Someone will chime in with a better answer than that. Other than that I think it will definetely be a fun truck to drive. Any type of porting done to the heads?

[1low94]

Thanks for the info, as far as I know they are stock 6.0 heads I don't think there has been any porting done to them. I guess I can't complain too much for what I paid. I guess I never thought too much about the cam vs weight thing, but you may be right, I'm not looking to stick a bunch into the motor but would be open to suggestions, I am doing this build with the intent of having a bad ass motor that still gets somewhat dec mileage because I drive it long distances to attend truck shows and have ZERO intrest in building a trailer queen. But like I said if something will work out better I am def open to suggestions. Thanks guys

With those plans I would definetely pull that cam out and put in something smaller. I'm building a 6.0 with ls6 heads and a comp cams lsr cam. Look into one of those cams maybe. You can probably sell thatms4 cam for a fair amount especially if it is new. I drive my truck everyday to work in socal traffic and have no issues with the set up I have in my sig. It makes good power for what it is but I want more. You will be happy with the 6.0. When I finished my swap and drove mine for the first time it was a night and day difference between the 5.7.....and I went down to a 5.3. Good luck with the swap and feel free to pm me with any questions.
