Default Dynamic compression help with Tick SNS Stage 2.
I used an online calc, and i'm getting a scr of 10.544 and a dcr of 9.021. Is this right? This is using the specs from the cam card i.e. IVC 39.5 ABDC.
unmilled 799 heads
fel pro 1161 gaskets 4.1" bore, 0.041" compressed thickness.
Stock bottom end LS1
Tick SNS stage 2 227/235 110+3

You’re using duaration at .050” numbers. The IVC @ .002” would be the right number to use.

I was just using the values that came on the cam card. I guess I'll contact Tick to get the right numbers.

Tick cust service said that my DCR should be around 8.4. I got the same number by adding 25 to the IVC number on the cam card.
