i've got 11.97 SCR and 8.64 DCR using a Comp XE-R 236 intake lobe for reference. DCR using a 238 lobe is 8.55.
i also used -.007 on the deck height and assumed there was no advance ground into the cam.
if you are getting 9.33 in your DCR calculations, you are probably treating the dish on your pistons as a dome instead. the ci's for the pistons should be a positive number, not a negative.
