Not Ranked
I'll say this once more-not sure if the OP is even watching anymore. This is solvable without going into the engine or running 20 degrees total.
I say this because every day I used to document engines' performance on DTS dynos. The bulk of those had these parameters: 91 Octane Shell pump gas, 10.75 to 11.3 CRs, 427 to 632 C/I, AFRs from 12 to 14, aluminum heads, smallest carbs were 850's, biggest were 1050 Dominators. HP ranged from 560 to 825. All cams had 108 to 114 LSAs, were SFTs or juice rollers and had advance from 28 to 36 degrees. All were tested under load and none pinged or ran hot. NONE used octane boost. The drag engines had 12.5 to 14.0 CRs and ran on C-14.
Doesn't it just make sense to try the simplest, least costly, proven suggestion???????
