Small Block 396 Piston Question
I know a number of you guys have built 396ci small blocks out 350 blocks but I was just curious about the pistons. Most of the rotating kits I'm seeing use pistons that require the use of an oil support rail for the bottom ring since the wrist pin has been moved up in the piston so far. Are there any concerns with this for a street performance motor? On a racing motor that you know is going to be torn down more often than a street motor I don't see an issue with this but I was just curious about this configuration for longevity in a street performance motor?

Those spiral locks have always kicked my butt, so I had the shop install them for me.
