LS3 Build So, I have decided to build my own LS3 instead of buying a crate LS3. It's going to be a lot more expensive because I'll be buying performance parts off the bat... but at least I'll be buying it piece by piece by piece instead of "BAM $7000 right here right now maddafakka!" 
any one else feel that this is the way to go?
any one else feel that this is the way to go? I got my plugs for TSP and i feel like they were much cheaper than $50 bucks...but if a performance motor is what you want, then yes, building it yourself the way you want it to be done is the way to go

I'd like to to see a link to where you saw that because the the closest think to that is a bare LS3 block for $1599.99. The cheapest LS3 short block I can find in TSP's site is $4274.99.

Its best to buy it complete. That way you are ready to install. Buying components will take time and I am sure you can save few bucks but it will cost you time....how fast do you want it in the car running?

Monte/Vett I posted about a install with a LS3 & 4L65E Connect & Cruse package from GM in my MC SS AEROCPE. I used all new after market parts which was cheaper than useing old parts. The after market has everything needed but took a lot of research. HOLLEY has the best parts for a LS swap. (I forgot to mention with the new GM package theres a 50,000 mile warranty)

It just depends on what you want to do. if you want to build the LS3 with performance parts And pick them out I would say build it yourself. Unless you have the money to go buy a nasty crate motor from a company like Mast motorsports
Have someone build it all at once if you have the means to, otherwise buying a part here and a part there is the way to go for sure. It will save over the long run but will definitely take a little longer to get it up and running
