DCR Question I've been running the DCR calulator for my new setup and I have a question about what kind of results do you get when you raise the DCR value. I just bought a new shortblock with -2cc relief piston,TSP PRC LS6 Stage 2 heads and a MS4 on a 111. According to the results I came up with.If I run a
.054 gasket my DCR would be 7.79-1
.040 gasket my DCR would be 8.05-1
.040 gasket adv. +2 DCR would be 8.21-1
.040 gasket adv. +4 DCR would be 8.36-1
What kind of results would I see? Will my powerband come in quicker or would I see an improvement all the way across the board? Patrick said that +2 would still pull past 6500 ok and that +4 would give out around 6500. So what do you give up and what do you gain by advancing this cam?

The thinner gasket will tighten the quench area on the chamber, aiding in detonation prevention. It will also raise compression a little bit obviously. By advancing the cam you give up a bit more top end in exchange for a better lower end.
