Could someone please post the formula to calculate the SCR & DCR for the following LS1 engine.

Stock Pistons
AFR Heads Milled to 62cc
Stock GM Gaskets
218/224/114 cam

Thanks

 

There is a calculator in the stickies on this page. Smokemup, a sponsor in the links on the right has a nice engine math section. You will need more data to accurately find your dsr.

 

Well, assuming a couple of things, your DCR should be right around 8.93. This assumes a seat to seat of 260 degrees on the intake lobe and a +3 on the pin angle.

Your static compression would be 10.9:1. If you can get me the intake actual duration and the installed angle, I can get you a closer number.

 

Thanks!

Would that info be available on the Cam Card?

 

I get a DCR 0f 8.39 with zero advance ie 114+0 with comp lobes.
