5.3 with 4.8 pistons

[AGearHead4Life]

When building my 5.3 I had my 4.8 pistons bored and pressed on 143 LS1 rods, engine runs great in my 81 K5 with stock lapped 862 heads and fbody manifolds. Don't quote me but I believe the L33 flat topped pistons are the same p/n as the 4.8 flat topped pistons. Either way they will work, Good luck with you build.

awesome. Sounds like a cool build.
