Hey guys, I upgraded to a stroked 512 last summer and now I'm looking to upgrade the fuel line with PTFE braided stainless. Factory lines are 5/16" supply with a 3/16" return. Motor is pretty docile with having untouched Eddie heads and a 239 @ .050" roller cam in it. Future plans include pulling the heads off for CNC porting and a 600HP FiTech - won't be going beyond that, so room for upgrades beyond this level would be unneeded.

I was thinking 3/8" supply and 1/4" return. Opinions? Thanks guys!
