360 Engine Build Guidance (Boost Maybe?)

It all depends on how much boost you add. You can still make OK power at 8 to 1 and add boost later. Extra ring gap won't hurt. Personally if I was boosting an engine, I'd not want more than 8 maybe 8.5, so you're not limited to only 5 or 6 lbs of boost. This is a really basic approach. Things like quench, cylinder head material, camshaft, intercooler, ignition retarding under pressure, all play a part in how much boost you can add.
Get the book Supercharged by Corky Bell. Good information. Also watch some of Richard Holdeners you tube stuff.
