5.3 overhaul

[04white-z71]

Hey guys a recently pickup a 07 suburban that has a bad hole. I've called around and cannot seem to come up with an engine for it. I'm thinking about punching it out. 020 and doing a mild build. Thoughts on the best place to source the parts?

Summit Racing maybe? Are you now going to delete the AFM system? I've considered someday turning mine into a 402. You might find that a junkyard LY6/L96 is less expensive.

I've been trying to find a junkyard motor with little to no success. From what I read I can punch it out to a 5.7 pretty safely. AFM and dod delete. With a mild cam and it should make respectable numbers.

I've put together a list of parts but not where to get them yet.

Started a build thread. Decided to go all the way to 3.898 or 5.7.
