Thanks,
I ran my current 350 through and the one I plan to build, my current motor came out at 8.1 DCR and 162 PSI, actual cranking compression is an honest 160 so that's pretty darn close. I have run it with 87 Octane with no trouble. The one I am planning came out at 8.4 DCR and 170 PSI. Think the extra .3 DCR and 10 PSI will make that much difference? I'm thinking the "real world" numbers will probably be a bit lower. The new motor will have headers, better ignition, intake manifold and will be backed with a 200-4R and 3.73 instead of the tired TH350 and 2.73.
