Anybody know if someone makes a forged piston to fit a stock 5.3? I don't want to pay for custom pistons or have it bored out and I think good ol' #7 took a crap on me.

Poor fuel distribution I think. What ever it is, it sucks!

You won't have poor fuel distribution in a port-injected engine, similar to what was experienced in the old carburetor days. It is probably related to a cooling issue, which could make #7 more prone to detonation.
I knew it typically ran hotter than the others and just figured it was a fueling issue.

#7 is the leanest because it's the hardest to get fuel to with stock rails.
I knew I heard that somewhere!!

So if i upgrade rails i will not have that problem? If so what rails do i need to get?
