Can any of you guys with LNC2's tell me about your before and after differences when you went with higher compression pistons and porting/polishing the cylinders?

Scotty G,

 

Before any of those treatments, most had more money.  During the last century, I was told that the biggest bang (now, now Walter) for the buck was from higher compression ratios (within reason) for NA engines.  The other improvements require a more thoughtful treatment of the entire induction system for real benefit.  EIs count, too.

 

Some use ECI cylinders where ECI claims porting improvements (flow).  Some will say that is BS.

I don't think many have made such mods on their current engine and then reported pre/post performance.

There is more to performance than brute power - although not much more.
