I just checked mine. All cylinders are 200-207. Does this seem high? It's supposed to be a 10.3 to 1 compression ratio engine. It's a 351W with the complete Performer RPM package.

Those are good numbers. :) Excellent cylinder filling going on there. ;)

What you want is to have all cylinders within 15% of each other.

This test has nothing to do with your static compression ratio.

Fresh build on the engine? Which cam comes in that "package"?

Yes, 150 miles on the engine. The cam's a dual pattern, 496/520 lift, with /224/234 duration @ .050".

Nice job!

If it were me, I'd have a chassis dyno done and dial in the timing and a/f ratio.

Done once...done right (hopefully ;))...good to go! ::

I think I'm going to (dyno tune). It's probably worth the $ to have it done and not have to be experimenting myself.

Thanks.
