Raising CR on M30B35

[632 Regal]

Raising the compression alone will not give the gains you are thinking. You would need to do other things in combination to help the compression such as exhaust, camshaft, intake etc.

Of course, I'm planning to make other mods as well while the engine is being overhauled.

I don't actually expect much from raising the compression... if I gain one MPG and a few HP from it, I'd be satisfied Anything more than that would be quite welcome, but I'm not really holding my breath...
