6.0 swap please help.

I've got planned to do a 6.0 swap into a 94 Z71 no parts or engine bought yet. Here's what I know so far correct me if i'm wrong.

1. 6.0 will drop in after I buy motor mounts, any vendor recomendations?
2. Will need flywheel to bolt to 4L60E, mine is fairly new and this isn't no hotrod so I'm going to use it.
3. Will run current radiator and add electric fans, its a larger rad from a newer model Tahoe.

LOL yea I don't know much. Here's what I don't know.

1. I will be using an after market intake (Edelbrock) and a self learning TBI set-up like projection or fast. I think Holley will have one out 1st of the year also. I like the carb look. I should be able to use the cruise and throttle cable without any mods.
2. I think the factory 6.0 manifolds will work and have my current exhaust configured to fit.
3. Will use a truck engine, How are yall running the A/C lines from the 6.0 compresor?
4. I have no clue how to wire my factory gauges to this engine.

Well there it is any help would be great.

1) Why not use the stock EFI from the LS motor?
2) Sounds good, but if you're looking for slightly more performance, a site sponsor makes CHEAP longtube headers for this conversion.
3) Ask Redheartbeat
4) See above.

Somewhere around here there is a giant thread about this swap. Almost everything is covered. I suggest reading that thread and then posting any questions after that. I bet that helps you more than anything.

I went ahead and pulled the link for you... Good luck sir.

Don't really know anything about the factory EFI and running all the wires. The aftermarket set-up seamed the better route plus if I replace the current motor with saaaay a vortec I'll still want to upgrade the TBI, I hate the performance of that thing it's just a stupid 2 barrel, but they do run flawlessly
and are dependable. So taking into account the price of a rebuilt engine plus the injection. The 6.0 (used) plus the mounts, adapters, and flexplate comes to about the same money. Who knows I may just find a used 3/4 ton and give this one to my son. It's paid for so i hate to buy another and I couldn't trade this one plus the cost of the build for a 3/4 ton 6.0. Don't want headers on my daily driver just personal preferance. Oh yea THANKS for the thread I'm going to read over it right now.

Keeping the LS EFI is super super super easy. It would be much cheaper, more reliable, and have better fuel economy. When you upgrade to an LS based motor, there is no need for TBI anymore. It's a much cleaner, easier system with the LS motors.

The cheaper part is true for sure the Fast unit is around 1900.00. Figured out how to use the factory 6.0 compresor with my A/C. Docs Blocks has the answers, adapters and such, I can just splice the lines or make new ones I think they also will make custom blocks if you call.

Everyone who has done the conversion on here has just stuck to the stock LS EFI. It's proven that cost vs. performance of switching isn't worth the FAST system. You aren't looking for massive HP anyway, so I still suggest sticking with the stock LS fuel delivery system.
