Looks like a solid plan. If there are no plans for boost in the future I would shoot for a buy more compression. The stock engines run on 87 octane just fine at 9.5-10:1 compression and if you have good higher octane fuel you may be able to go a bit higher than that.

We have 97 octane but with compression over 9.5:1 we have problems exhaust temperatura control. I climb up on sand hills by 400 to 700 meters on Atacama Desert
My plan the next year is go for boost(sure change RC 8.0:1 aprox)

Hi, I installed the stroker with the new camshaft and GM VVT phaser limiter, but this cam has ICL 111(LSA114) and I used phaser with limiter nothing else, so I“m looking for a timing set to correct cam perfect instalation.
