Has anyone dynod a 355 chevy, around 9.5 to 1 with a cast iron 2 barrel intake and a rochester carb?? Also wondering if you have tested with an alternator and without on a HEI. I know they say it doesnt make a diff with the msd, and i have always ran an alternator, but with my new pulley system, i dont have alot of room to move alternator back. .Any input ?? Thanks for any info guys.
