63 Chevy Truck Project Help Greeting All LS Owners,
I have a 63 chevy truck and I want to go fuel injected. I wanted to do a supercharged LS2 but when I found out I would be out of close to 12k I had to rethink my inks. Here's what I have been considering:
Just doing a LS2 and dropping it in stock.
Building a LS1 to get some pretty good numbers
Building a LT1
I have never gone with a fuel injected setup and I have sooooo many questions about what to do and what to look out for. If anyone has any knowledge on this subject please please give me some insight thanks

Put a carburater on it and you will have more hair on your head and more money in your pocket. I sure i`m glad i did and my carbed LS motor made more hp then the F.I. motors with the same specs. All i did was time it and jet it and i have not touched anything in 4 months i love it.

I know lots of people go carb'd cause it's easier and cheaper, I went efi cause I never got along with carbs. So I can understand wanting to get away from them.
I am thinking about building a older chevy truck soon (advanced design series) I was most likely going to go 5.3L with a turbo setup. You can supposedly get dropout 5.3l complete for around a grand, add a cam, turbo, etc. and you are doing pretty well. Supposedly the weight difference between the iron block 5.3 and the Al block 5.7 or 6.0 is around 80 lbs, and the hp difference isn't that great after some parts and tuning. You will have to find a tuner locally or get mail order tunes I guess. You could also get a tuner and learn yourself but that'd be a steep learning curve for someone not familiar with fuel injection.
The easiest option would be get a LS2 in there and then save up money for upgrades in the future.

I want to put out more horsepower than my chevelle. I have a 454 ls6 motor in that car and I can pull an LS2.. I have heard that with a few mods the ls2 can do some pretty amazing things. Does anyone know of anyone who has built an LS2 and what kind of HP they have? Also with the EFI should i do an aftermarket ecm and harness or try and find the harness and ecm that come with the motor out of the car it was pulled from?

If you know how to use it, HP Tuner is probably the best software for LS computers. I've heard it's kind of confusing at first, but not too bad once you get the hang of it.
