I'm going with a Delta 260 cam for ease of installation and the modest gains I'm looking for.
What compression ratio should I be aiming for?
I can't find any stats other than Crower recommending minimum 10.5 for their stage 2.
Would 10.3 be more than enough for the 260?
It's better to be under cam'd than over cam'd right?

Setup is D16 block, A6 pistons, Y8 head, i/h/e

Thanks

 

You'll be fine as long as you're able to tune the motor after the addition of the cam. Compression isn't as big of deal as people like to make it...especially with the milder shelf profiles.

 

^^^ agreed. Compression plays a very small part in a huge equation when sizing cams. Yes it is important, but not .2 points important. Delta cams aren't "big" by any means. You will be fine.
