360 mopar, 9.8:1 CR, 175 PSI cranking with a Hughes hydraulic flat tappet cam: 238/244 @ 0.050, with nasty/crappy quench on stock heads. I run 93/94 pump gas...pretty aggresive advance curve: 21 [Email]idle@900[/Email], 35 @2000. No ping.
I would advance final timning even more on that one. All my low compression 340's and 360's liked at least 38...
And for the nay sayers, you can run 14:1 on pump gas....Its called water injection and it works really well. If you can tune a carb, you can tune a water injection system. We have guys tired of paying for race fuel and went this route and will never look back.
