Engine Build Tech Help

I have a Hughes engines hydro roller cam to put into the motor, I failed to break in my cheap cam swap earlier this year, so I decided it was worth my money to not worry about breaking in a cam. PN: HUG SER1822ALN-10. Since the only numbers I have for this cam say it intake close is at 35* ABDC, I plugged that into the dcr calc. With the static compression ratio right around 9.0:1, I am getting a dcr of 8.4:1 at sea level

Hang on - the Hughes cam timing is at 0.050" lift, the valve will not be closed at 35* so it will be inaccurate for DCR calculations. Call Hughes they should be able to tell you what the actual closing point is if the 0.006" timing is not printed on the cam card.
