Build recommendations!! I have a 80 model c10 that I would like to swap. I’am just looking for some guidance to get started. My goal is 4-500hp for now and adding forced induction (turbo) later on. My question is, what LS would be good to start building? I’m trying to keep in mind which one is more common (as parts would be readily available) and which one won’t break the bank to build. I was leaning toward the LS6 but could use a little push in the right direction. I’m a heavy truck/equip diesel mechanic, so I don’t see these engines everyday to know what to expect.
Thanks in advance!!

Whats your budget on acquiring an engine?
The LS6 is going to be expensive as are all of the LS aluminum block engines. Most would take the 100 lb weight penalty and go with a iron truck block engine like the 5.3 or 6.0. Parts are readily available and a lot will interchange between engines. I payed $1100 for a running 120,000mi "LQ9" six liter that ran perfect. Went through it with new parts on the fresh build.
400+ wheel hp is not that difficult n/a. Higher hp... you'll need a set of cnc ported heads or a set of aftermarket heads to increase flow along with a good intake, longtubes and camshaft.

Thank you!! That’s the type of info I’m looking for! I don’t mind the extra weight to save a few bucks. I know a lot of people swap their c10 with the 6.0, probably because of that reason. Can these engines handle boost stock? Or do you need to upgrade the bottom end?

You can get the C-10 to LS engine conversion headers from SPEED ENGINEERING
The iron stock bottom end LS can handle boost. Check out Richard Holdener's Youtube channel for a ton of turbo, supercharger, nitrous, heads, intakes, exhaust, camshaft dyno testing. Matt Happel also has some great stuff over at "Sloppy Mechanics" wiki and Youtube channel.
