4-53T Silver Series upgrade

Some of the differences between the Green and Silver 4-53T. Crank, camshaft, head, liners, pistons, connecting rods, timing gears, blower with a 6-8 psi bypass, turbo and valve cover.

Nice overview of the differences good Sir! Those silver rods look like they're brand new! You're running the Green liner with a custom Green cam correct? Cheers!

The new piston/liner combo looks way longer. Still fit?

I'm rebuilding 2 4-53t's for my boat- is it worth it to convert them to silver series? What's the cost difference vs performance difference? Thanks!
