That cam has a super late intake closing. After plugging that info in a caluculator, I'm getting at SCR of 6.8 at a DCR of 10.17. Was that when you swapped to 0.075" gaskets? Advancing it 4* would bring the SCR up to 7.1. And with the 0.528" cam I get a SCR of 7.65. Sorry, just trying to keep all of that info straight so I can make use of the information.
I think my issue is the cam I plan on running has an intake closing at 67*, so it doesn't bleed off as much compression.
Thank you. I appreciate the feedback. I'm hoping I don't end up having to replace the pistons with the Autotec version with the 4.1cc larger dish and re-balance the assembly. If that's the case, I'd rather do it now with it apart. Do you think 8.24 SCR will be an issue (in terms of detonation) with 91 octane and 0.039" quench? At this point, it's well beyond my expertise.
I'd hate to think it will only work with a perfect tune on a cool day under a specific set of circumstances. I'd rather have soom wiggle room for error (bad batch of gas, engine gets hot - I am in Sacramento CA after all, etc.). Obviously **** happens, so I'd like to have at least some wiggle room.
With which scenario?
