Pump gas and compression; With these big cams there is a lot of bleed-off
from the high percent of overlap which in turn lowers compression and
with the alluminium heads which you can run more compression makes it
able to get away with the higher compression if that makes any sense.
All I kmow is that it works for me and a lot of my friends in the same situation
I've always used race gas when dynoing my motor for the ease of reading
the plugs, they stay cleaner but the next time I use the dyno I'm going
to run pump gas first and the race gas and maybe even E-85 just to see
what kind of power it makes over gas.
And some thing I've found that usually any thing under 200LBS of
cranking compression is usually safe for pump gas. I hope this helps
any one trying to run pump gas and higher compression.
