what to do with my 273

greazerlou and gotdart,
I agree with both of you, but as gotdart has stated they share the same stroke and different bores. I also agree with gotdart as the smaller heads will benifit the littler engine more, but I would use a hyd. cam instead of the mech. type as the torque would be higher due to less overlap.
904s come with a lower gear than 727s stock any way, so this is a plus to start with. The rear gear will just make it that much better. Both have very valid and good points.
