I'm glad you found a solution. I may end up in the same boat. haha. I'm curious though - At the time you were having issues, did you ever consider retarding the cam 4-6 degrees? That should've lowered or dynamic and effective compression considerably with minimal expense. It would've been at the expense of a little bottom end torque from my understanding, but with a stroked big block that may have actually been a good thing in a street car.
Just playing with a calculator, it seems that retarding the cam in my SB build 4* would lower the dynamic CR from 8.25 to 7.98 and the cranking pressure from 170 to 163 psi. That seems like a great option should detonation issues arise.
Okay, so your numbers you posted above are based on the equivalent to our 93, so it's a bit apples to oranges. Unfortunately, I'm limited to the same 91 pump piss as Kerndog. I appreciate the info though.
What do you mean "preferable?" I'd like to keep this focused on detonation resistance based on the components of my build and I think we've already established that a quench motor is more resistant to detonation than one without quench at a given compression ratio. The question I was trying to get input on is which of these combos would be less prone to detonation.
- 10.02 SCR/ 7.91 DCR w/ 0.059" quench (161psi calculated),
- 10.17 SCR/ 8.02 DCR w/ 0.052" quench (164psi), or
- 10.45 SCR/ 8.24 DCR w/ 0.039" quench (170psi calculated).
