I've been trying to figure out my DCR and quench and something doesn't seem right. Been using a DCR calculator I found on here but my it comes out pretty high.
Here's my setup.

LQ9 w/ 317 (all stock)
230/224 .575/.563 111 LSA (I'm guessing ICL is also 111 because I believe this cam does not have any advance ground into it. Please correct me if I'm wrong.)
Not sure on which head gasket yet, because I don't know where my DCR is at. So I just entered in a stock GM gasket (.054 I believe)

Hopefully the attached files show the numbers I entered in. Can someone tell me what I may have wrong.

 

Your advertised numbers are wrong. The advertised numbers are the numbers at .006" not the ones at .050".

I'm guessing a Comp XE or similar lobe, so with that (all your other numbers are correct), your DCR is 7.5:1.

 

Oh no ****.

I could have sworn that advertised was at .050"


Ok, now would anyone happen to know that spec since I don't have the cam yet or cam card?

EDIT: 7.5 seems low. This will be my daily driver, I was thinking something between 8 to 8.5.

 

What number did you use, so I can try out different head gasket thickness's?


Oh and what about quench or should I not even worry about that?

 

You're at stock compression. Quench isn't as big of a deal. Get up over 11:1 and you'll need to be concerned with it.

I used the Comp XE numbers, which are 53 degrees higher at .006" than they are at .050".

 

Good deal bud.

I just wanted to get a little more SCR out of it without screwing up my quench. I should be able to use a .040" gasket without problems right?

 

I'd use the Cometic .045" gasket.

 

Thanks for your help Jake.
