69 Camaro LS Motor SOON!! Hey guys, new to the site....have a 69 z28 that i want to put an LS motor in. The car has a 350 in it now with a Tremec tko 600. I'm not looking to go over the top, just want the modern setup. Probably a 6.0 truck motor (HP of 450-500) My questions are:
1. If I go EFI, factory or Fast EZ EFI? Which setup is easier to setup?cheaper? I know the fast system is 2 grand, but with the factory needing wiring kits, pcm work and tuning, it seems that could get costly and confusing.
2. Looks like alot of guys do the carb'd conversion, what do you gain with an LS motor over a carb'd sbc or bbc?
3. Lastly, do I have to convert my mechanical clutch to hydraulic? What all is involved? Do I need a special bellhousing for the hydraulic setup? I've seen the OEM setup and the Kiesler setup.
Any help or suggestions would be great, I've been looking at past posts for ideas. You guys have some great cars!
Thanks,
Zcrz

im building a 67 with a 5.3/t56. i would go with factory efi. my harness and cpu was only 500 and very easy to install. two hot, two ground and ready to go. came already tuned and everything. not sure y people go carbed i guess cause its easy and electronics scare people but efi is definitly the way to go. as far as the clutch it depends on what u mean. if your putting a t56 in it then yes you do because the slave cyl is hydralic. if ur using an old 4 speed or something then theres a way to make it work but its complicated. i just went with the t56 route. heres the link to my car

who did you buy your harness and pcm from? I like the stock efi as well, just scared of the electrical and tuning i guess.
The tranny i'm running is the 5spd tko 600....just wasnt sure if i had to switch to a hydrauil setup or not.
Thanks for the input....i'll check your link out..

I put a 6.0 truck motor and 6 speed Richmond trans in my 68 vette.
If you want to keep your Tremec you can keep the Z bar linkage. You'll need a 621 style BBC bell housing, preferably one with an adjustable throwout arm stud. I got mine from Keisler with the additional bolt hole at the 12 o clock position. The LS1 flywheel/clutch will bolt up fine. The LS7 pilot bearing will fit the crank and your trans input shaft. A longer throwout bearing provided better geometry than the stock one in my install.
Also, it will be easier if you get the 1" setback motor mount plates to keep the trans as close to the original position as possible.
As for the rest of your questions, a lot of the aftermarket and carb coversion can provide mor hp but that would be primarily over 5000rpm.
I used a 350 hp LQ9 with headers and a retune on stock computer. It's probably near 400hp and will over power the rear wheels as is.

^^^NIIIICE!!!!! You answered some of my questions regarding a Richmond-6-speed swap! Thank you, kind sir!
I'm doing a 69 RS/SS with a 408 (stroked 6.0L) and L92 heads. Based on my research, carbs seem to make more peak hp than fuel injection. I will have a 4-bbl intake with a EFI, 4-bbl., throttle body for my set-up though. Fuel injection IS the way to go!
I will probably go with an aftermarket ECU set-up, depending on local tuners ability. I hear that the after market EFI/ECU systems allow more tuner "options", if you will. I have no experience with the EFI stuff yet, as I am no where near that point in my swap.
Originally, I planned on using a T-56, but the TKO 600 (hydraulic clutch linkage) and Richmond 6-spd (with mechanical linkage) were the other avenues that I was going to explore.
Whatever the case, research, research, research before you spend a dime!
Good luck with your build!

If you use a truck bellhousing then it has the top bolt hole the 621 is lacking. You can sell the 621 for enough to buy 3 truck bellhousings. I believe the truck # is 403. You will be missing 2 bolt holes if you use the 621.

i got my ecu from a guy on ebay that builds them. came with custom harness and programmed ecu i payed about 575 shipped so i was happy since painless wirings is like 1000 for just the harness less the ecu and programming.

I used the C5 OEM exhaust that came ON the LS6 vettes.
I initially had the 1" setback but changed to the plates that share the bottom front bolt hole between the SBC ans LS mounts. The ROD trans fit better with that mount. I redrilled the Z bar mount on the frame about 1/2" forward and the block mount 1/2" back to keep the linkage strait. Btw, I used Speedhounds LS Z bar mount.

I just bought a complete stand alone harness off of ebay for $498, mine was $49 more because i will be using a 4l80e. Havent recieved it yet, but the guy i dealt with was very to do business with and responded to emails/questions very quikly. A search on ebay for ls1 wiring harness will take you right to it, the company is called psiconversions
