Thread: i need cam selection advice..

Tweet

Tech inspector, I just want a cam that makes the most power that I can get.with the equipment I listed earlier in this thread.i am new to this like I said.i had no clue that a Lopey sound bled off cylinder pressure.i just thought it sounded cool.did not know it would have negative results.maybe you could help me then?..I do not want to detonate my engine with this cam.because my machinist told me that my heads are 68 cc and he also told me that they had been previously milled.and I have 4 valve relief flat tops.so I have a feeling that I might be a little bit over 10:1. I really need help ..

As I said, you need to know the static compression ratio of the motor before you can intelligently choose a cam for it. Did the machine shop guy cc the chambers? Can you get a photo of the piston crowns and post it here? Not trying to bust your chops here, just want to teach you how to do it correctly so that you can teach others.
