Tuning For Detonation

My slanty is only 9.5 and I went down the same road, with a smaller cam, much smaller. Sorry, that engine was assembled in 1994 and the only parts I remember are 9.5Scr, short Power-Timing, Late stall-timing and 87E10.
A SuperSix 2bbl intake, but not set up for power, rather, set up for fuel-economy. I ran her at a minimum coolant temp of 195.

I hope you can achieve your goal

BTW; I still have that 1980 Volare,(going on 27 years now) and this spring it fired right up with just a lil fresh gas dribbled into the intake. Probably the best starting carbyd engine I've ever had, and the only reason I haven't yet hauled away that rusty hunk of junk . Oh and the trans has been thoroughly de-bugged as well.
