For everything needed a good running engine is reasonable mileage that is not a bad price.

Aww shucksFor everything needed a good running engine is reasonable mileage that is not a bad price.
Please forgive me if you have already considered the following info, but this above statement worried me just a bit. I will start by saying I have no idea of your mechanical abilities, experience, or budget. Just like you have no idea anyone on this sites experience or how much of the knowledge we are giving you is based off a friend, a magazine article or tv show. We can easily sit back and spend your money and tell you what "we" would do from our keyboards.
All that being said, I just want to make sure you think about a few things before you go planning on this build. Set a budget then add about 800-1000 to make it more realistic because there is ALWAYS expenses you don't plan for and they will nickle and dime you to death.
Next to Carl I am one of the biggest LS fans on this site. I'm all for you jumping off on that build but just remember that $1000 for the engine is just the start...
The truck you are want did not come with a LS motor so you will need a new...
Oil pan
headers- May be a custom build not sure who makes a set for this swap
If you want to hit the 350+ hp range Cam, timing chain, may be lifters
Intake manifold
Carb
Fabricated motor mounts
Gaskets
oil
plugs
will the ignition coils still be good and you'll need a set up to fire them
accessories - Alternator, power steering, AC, etc.
What transmission will you run? Will it need an adapter plate? If you go with a 4L60, 4L70, or 4L80 you will also have to change the tranny crossmenber and new drive shaft.
I'm sure I left quite a few things out.
Again, if all this has been considered. I'm sorry to waist the space. Some of this is a given with either a LS swap or Gen 1 sbc. But the truck would have most likely came from the factory with a SBC and there will be much fewer custom parts needed. I'm all for the LS and I look forward to a build thread anyway you go.
